Does Everyone Need a Portable Printer Scanner?

admin — Thu, 29 Jul 2010 13:51:10 +0000

Having a portable printer scanner offers the benefits of having a printer and a scanner with you wherever you go. This is certainly a boost compared to portable printers and portable scanners. If the question was changed into “Does everyone want a portable printer scanner?” then the answer will be very simple. It will be a yes because everyone wants something new and a portable gadget that is both a printer and a scanner is certainly something you don’t see every day.

Benefits of a Portable Printer

A portable printer certainly has a lot of uses especially if you are in a profession that requires you to travel a lot. Most people who will find this useful are traveling businessman, salesmen and photographers. Fortunately, for people like these, portable printers that are recently released offer printing speeds and resolutions compared to that of a standard desktop. The latest mobile printer released by Canon, the Pixma iP100, offers a resolution of 2400 x 9600 dots per inch. This makes great for printing photos as well as sharing them. The one released by HP currently has the highest printing speed for a mobile printer, which is at 22 pages per minute. All these features come in sleek design, which makes it very easy to store in the luggage.

Benefits of a Portable Scanner

Unlike a portable printer, the need for a scanner is not as frequent compared to a printer. Of course, there are professions that will require you to scan documents wherever you go. However, in cases where a lot of documents need to be scanned, there is usually an office involved and most offices have their own scanners. The smallest scanner in the world is about the size of a pen and you can scan any document on a flat surface. You can scan pictures, papers, IDs. It is certainly very handy whenever the need to scan something arises. However, how often does that need come up?

Needs versus Wants

A portable printer scanner is one gadget that is not very common. Most people are caught up with the hype of new things, like who’s got the latest gadget or who’s got the better gadget. We need to establish that what we need is different from what we want. Most gadgets that are coming out in the market today are expensive and sometimes luxurious. One point to consider though is that when we really need something, sometimes the price becomes reasonable. So it is important that we buy such things out of need. More often than not, most customers buy these types of gadgets, using them frequently for the first few weeks and ending up at home along with the other gadgets.

A portable printer certainly offers the advantages of having a printer and a scanner and having them with you whenever you need them. However, these features always come at an additional price. Unless you travel a lot and your job entails you to print and scan at the same time, having a portable printer scanner is nothing more than a luxury.

Mr. Johnson specializes in finding the best portable printer and scanner for personal and professional use. Choosing a printer that can also scan is not something that should be taken lightly as the wrong choice will not only make the task a pain, but it will also be a waste of your time and money.

Repairing and Servicing the HP DesignJet Printer and Plotter

admin — Tue, 27 Jul 2010 11:34:05 +0000

It seems only yesterday that HP introduced their first large scale poster plotter to the IT world – but in fact the year was 1997.

The DesignJet 2500 was the first in a long line of HP Plotters, which enable the printing of high quality documents in large scale. The technical issue of feeding large sheets of paper and storing and delivering the required high volumes of ink had been finally overcome. Since 1997, the products have become ever more sophisticated, coping with both improved quality and print speed that the modern user demands.

The DesignJet 2500 was followed up by the DesignJet 3500 whose unique feature was that it was able to print onto paper widths of 54 inches using the ink jet method of printing and since then the quality and performance of the HP DesignJet range has continued to be enhanced and improved.

One of the biggest issues for users of these machines has been the Total Cost of Ownership of these high initial investment business tools. The initial cost is of course the major investment, but the ongoing cost of keeping these machines running in terms of maintenance and ink can also be significant.

For this reason many organizations will often contract with a specialist supplier of plotters to look after their mission critical “super-printers” – and these contracts often specify response and fix times so that users can be assured that their plotter will not be down for too long in the business day. The cost of these contracts can be very modest when compared to paying the one-off charges of those same companies when they are invited to attend on an ad-hoc basis.

When working on an ad hoc non-contracted basis there is usually no question of a guaranteed response time, guaranteed fix time, or a replacement plotter pending repair. For most organizations a maintenance contract should be an essential part of their business continuity program.

In addition to routine maintenance it also makes sense to service a plotter at least once a year depending on the volume of printing and irrespective of whether there are any immediate issues. An annual service allows the pro active management of plotters ensuring less down times on a planned and managed basis. Often these routine visits can be secured at a reasonable cost if taken out at the same time as the more traditional maintenance contract.

In addition to maintenance and support services it is also important to find a good value but reliable supplier of the ink cartridges associated with your HP Plotter – very often the company which maintains your plotter will also supply the ink at competitive prices to ensure your loyalty and it often pays to ask them about supply before you shop around and commit to an unknown and potentially unreliable supplier.

When selecting a suitable company to support a plotter it is important to get some idea of their performance and learn what percentage of their site visits end in a complete fix – as well as the length of time to make the fix. Also try to get some recommendations and testimonials from other customers to ensure that the performance does live up to the promise.

A Guide To Ultrasonic

admin — Sun, 25 Jul 2010 06:17:10 +0000

Ultrasonic generally refers to acoustic frequencies above twenty thousand hertz, which is the upper limit of human hearing range. These frequencies are however audible to certain animals such as mice, bats, dolphins, and dogs that have a higher hearing range as compared to humans. The human inability to hear ultrasonic sound waves is caused by the middle ear that acts as a low-pass filter.

Humans would have been able to perceive ultrasonic sound waves if these waves could somehow be directed into the skull bone to reach the cochlea without passing through the middle ear. Deep-sea divers who are exposed to high frequency sonar signals above fifty thousand hertz sometimes experience this effect known as ultrasound hearing.

Ultrasonic sound waves form a part of many devices used in industrial and medical sectors. The most commonly used device is an ultrasound machine that is used in the treatment of benign and malignant tumors via a process known as ultrasound surgery (FUS) or high intensity focused ultrasound (HIFU). Medical research conducted to study the effects of ultrasonic waves on the human body suggests that the waves have the ability to stimulate bone-growth and has the potential to disrupt the blood-brain barrier for drug delivery.

Industrial devices also use ultrasonic sound waves to locate microscopic flaws in materials such as metal parts and plastics. Ultrasonic frequencies used in these devices usually range from two to ten mega hertz. Ultrasonic sound waves used in cleaning devices are usually in the range of twenty to forty kilohertz. These are generally used for cleaning jewelry, optical parts, watches, dental instruments, and surgical instruments.

Advanced research work is currently underway to develop a system for producing a phenomenon called sonoluminescence that has the potential to enable nuclear fusion reaction. This will provide a safe and cheap means of producing electricity and will help in solving energy problems faced by countries worldwide.

Digital Scanners

admin — Tue, 20 Jul 2010 21:51:26 +0000

A digital scanner is a scanning device that could trace photos, images, documents etc. It helps to make a standby soft copy of any document that is able to transfer through electronic devices and technologies. It is based on a technology called reprographic.

The basic operation of the scanner is to read the image of the object placed on the scanner pane of optical reading feature which converts the analog code into digitized code. The image scanned is practically measured by dots per inch (dpi).The scanned images are then transferred to PC, where we can edit or modify the object image. The images such scanned can be converted into any reliable format that a PC can support. There are a variety of digital scanners which include hand held, flat bed, film and drum scanners. Each varies by the resolution of the image they could produce. They vary from few DPIs to more than 6000 DPIs. The drum scanners alone are used for business purposes where a high end of scanning and reading of objects takes place.

The main technology remains is Optical Character reading (OCR), which is the brain of all the scanners. This is the principle of all digital scanners. With this optical scanning method, a ray of light scans the object on the glass pane thoroughly from end to end. Similar technique can be seen in the working of TV. But, both make use of different scanning mechanism. The object in the scanner can also be a real time object which some particular scanners allow.

The Hand held scanners are the one which are smaller in size and are used to digitize the images. The problem in them is that they produce a low quality image.

The flat bed scanners are those that have flat bed like body in their structure. The top of the bed is designed by an optical glass pane which has the mechanism to read the object on the pane. This is highly effective for bound documents which give high resolution from 4600 X 9600 dpi to 19600 sq dpi interpolated resolution.

The film scanner is a device, used for scanning photographic films and helps to feed data directly into the computer. This could do more than flat bed scanners to print the photographic images of any custom size. This could be done by specialized software and scratch removal hardware or software.

The drum scanner is used for capturing highest resolution from any images. It uses a drum or cylinder which spins at 1000 RPM, while scanning. A light source from the drum is used to capture the images. A Photo Multiplier Tube (PMT) is used to produce 10000 dpi resolution images. It also uses a three color drum RGB to capture the pictures and this is the first type of image scanner discovered. Because of high cost and rare usage, it is vanishing from the market.

This technology of scanning objects and documents reduces paper work much and increase the standard of reproducing same quality of images for multiple times. The advantages of these digital scanners are, anti-shake factors, fine scanning, speed and accuracy and digital imaging of any hard book without damaging the spine of the book. It is also portable and user friendly to handle and able to scan more documents than an ordinary scanner.

But, still there are some disadvantages at tolerance level in the areas such as distortions, low contrast imaging, reflections, shadowing, etc. Though, it has some tolerable drawbacks, it is highly effective at smaller organizations. It is because of a high resolution image production and sharpness of the image.

Optimizing Your Workspace and the HP Color LaserJet CP1518ni Printer

admin — Sat, 17 Jul 2010 01:51:33 +0000

The right printer can make all the difference in the way a workspace runs, like a HP Color LaserJet cp1518ni printer. There are many uncertainties in the business world, the academic world, the home office, or where ever a person plans to use a laser printer. That’s why the printer you choose should be tailored to the needs of your particular work area. A printer is usually an afterthought, especially if it’s the one that came boxed with the computer.

A color laser printer like the cp1518ni works anywhere that high-quality images (in addition to documents) are required at an efficiency and speed that regular printers can’t compete with. Anyone who does a lot of printing could make use of the difference in speed between a standard printer and a laser printer.

However, there are a whole lot of different laser printer models on the market with variations in size, speed, paper capacity, and a number of other features. HP’s cp1518ni falls on the lower end of the spectrum in terms of cost at three hundred dollars, so it is capable of a modest 12 pages per minute of black and white materials like documents or articles, and 8 pages per minute if the materials are in color, like a photograph or advertisement.

As for appearance, this printer sports a round silver and gray exterior and will strike the eye as being compact for its function. On the other hand, it’s quite heavy and cumbersome in comparison to, say, a comparably priced standard printer. This printer’s size suits its purpose and, despite those who find it burdensome, it can fit easily into the space another printer occupied.

Due to its size, no one should expect it to be able to process the volume of paper that a large office printer goes through. The input-tray holds around a hundred and fifty sheets and the output-tray holds around a hundred and twenty five. Additionally, it has a priority tray for special media, like an envelope or CD art. The printer isn’t suited for large offices or any large operation. It’s far more suited to small businesses, home offices, and the like.

The HP Color LaserJet cp1518ni printer can also work in a number of technological environments. It is compatible with Mac and Windows operating systems, as well as being built as a network printer. It is, however, a wired network printer, and is not wireless enabled. Nonetheless, setup is very simple with the documentation online. Some other nice connectivity features are memory card readers and a USB port for digital cameras.

One caveat: the toner ink for this printer, like that of all printers, is going to be expensive. Other companies’ toner is going to be similarly expensive, unfortunately. What matters is what you’re getting for your money, and in this case, the HP Color LaserJet produces high-quality images and text. The ColorSphere toner and HP’s new ImageREt system has impressed a number of shoppers and reviewers.

So, despite being relatively inexpensive for a color laser printer, the HP Color Laserjet cp1518ni printer will work for a number of applications in the office, a student’s dorm, a research situation, and elsewhere. It’s quite competitive with similarly priced Color Laser printers. When you need printer toner, you can either go online or go to a near buy store that sells HP Color LaserJet toner cartridges. LaserJet CP1518ni toner cartridges should be kept on hand so that when you run out it can be efficiently replaced.

Understanding KVM Switches

admin — Thu, 15 Jul 2010 19:34:43 +0000

A Keyboard, Video, Mouse i.e. KVM switch is a hardware gadget which helps the user to organize multiple computers from a single keyboard, video monitor and mouse. Although many computers can be connected to KVM’s only a few computers can really take advantage of the KVM switch device. Recently more devices are being supported with KVM capability allowing firewire and USB devices such as speakers and routers to connect to the KVM’s. A number of market ready KVM’s can also operate in reverse i.e. a single PC can be joined to multiple keyboards, mouse and monitors.

But the usefulness of KVM switches can be fully maximized when there are multiple computers in use, for example in data centers when different servers are in operation – multiple racks being controlled by a single keyboard, mouse and monitor. In this way KVM’s help data centers connect to multiple servers as they desire, without loss of control. In homes with the assistance of KVM switches; keyboards, mice’s and monitors of a home PC can be joined with laptops, tablet PC, PDAs, and Mobiles etc.

KVM Switches are some of the cheapest mechanical devices available in the market. These are based on multi-pole switches. They contain a rotary knob to select different computers. Typically KVMs allow sharing of 2 to 4 computers, but can join a maximum of 12 machines on a single switch configuration. One disadvantage of using mechanical KVMs is that, if a particular computer is not selected by the switch you can’t ’see’ a keyboard or its mouse. Users are also advised that during power failures when a PC reboots for a while KVMs will be unable to detect keyboards and mice. In the absence of a strong KVM signal, KVM switches fail to communicate optimally or at their complete capability for example if the switches signal is less than 100%, the multimedia keyboards keys on a keyboard would not be able to function properly. This could also affect monitors tied to the switch, in which screen resolution is affected and can drop as low as 800×600. There is however software options that act similar to KVM’s such as Virtual Network Computing (VNC), KaVoom, MaxiVista etc., these software’s facilitate switching hardware over network connections thus helping in reducing the number of wires connected. However alternative software also hold some disadvantages like pre-loading of additional software on each server in an endeavor to permit clients to remotely connect. If the server or pc/computer is busy, the software will stop responding to network connections. KVMs have one advantage over software alternatives – that is, they do not depend on any software, thus allowing remote connections. Contemporary KVM Switches use a minimum of 128-bit data encryption which is secured over WAN or LAN.

Buying tips: KVM Switches [http://www.comnauts.com/collections/kvm-switch]

* Look for hardware devices that you would like to connect to a KVMs whether, mouse, keyboard and/or monitor. Identify which port (USB and/or PS/2) your computer will use to interface with these devices.

* Choose a KVM switches that support all standard resolutions.

* Look for KVM switches that support auto scan intervals ASI and contain LED intervals.

* Make sure the switch you wish to purchase contains security features.

What is Really an All-In-One Printer? Pros and Cons of Owning a Multifunction Printer

admin — Sun, 11 Jul 2010 15:17:10 +0000

How does a typical office look like? You could have a scanner, telephone, fax machine, few PCs, and a printer. Now, all these can be costly and be difficult to maintain. If you want to save yourself less headache, you better get yourself a multifunction printer.

What are the benefits of all-in-one printers?

If you have been wondering why even Fuji Xerox, one of the biggest names in photocopying machines, decided to produce all-in-one printers, then here’s the answer for you. They have just discovered that there is a growing demand for multifunction printers, perhaps because of the following reasons:

1. You can have almost everything you need in one device. Why do we say almost everything? The chance of finding an all-in-one printer that has everything you need is close to nothing. Nevertheless, most of the multifunctional printers are equipped with either copier, scanner, fax machine, or telephone.

2. They are very easy to maintain. Because you have the equipment that you need in one technology alone, there will be lesser device for you to take care of. You will not have to keep a lot of manuals with you. This also means that you will not have to communicate with several offices to have your equipment fixed. If something is wrong with the scanner, you just need to contact the manufacturer of the multifunction printer. If you have a problem with the printer and the fax machine, it can be solved by one person alone.

3. You can also save space. One of the common problems with office equipment is that they are very bulky and they eat up a lot of your space. If you are not blessed with a lot of storage facilities in your workspace, you can make use of all-in-one printers. You also do not have to deal with several machines at one time.

4. You can save on costs. It will actually be more expensive for you to purchase the office equipment one by one than to buy a multifunction printer. This then becomes beneficial for your company, especially if you are trying to save on your expenses. You are also offered with extended warranties, so you will not have to worry about the overall maintenance of the all-in-one printers.

What are the downsides?

However, multifunction printers are not perfect. They do have issues that need to be addressed by their manufacturers as soon as possible. For one, one function can be compromised in favor of the other. Your all-in-one printer can print quality images, but it will not be an excellent choice when you want to scan some materials.

Moreover, there is a huge chance that you cannot use of the features simultaneously. You cannot print a document and scan another. You cannot send a fax message while your multifunction printer is still printing. The disadvantages, however, do not really erase the fact that multifunction printers are set to improve productivity and efficiency of your office. You just need to invest in one.

Why We Still Need SDHC Cards

admin — Fri, 09 Jul 2010 05:51:43 +0000

SDHC stands for Secure Digital High Capacity, and along with its variations is the most common form of memory card available for a variety of electrical gadgets and appliances such as digital cameras, PDAs, phones and Mp3 players. Most computers are now also compatible with SDHC cards and for those that aren’t there are still various forms of external flash card readers that enable you to browse their contents with your notebook or PC. Their versatility, durability and small size makes them particularly practical for small devices that are exposed to harsh conditions. However with the advance of technology, how to SDHC cards stand up, and are they still the number one form of storage?

SD cards became popular a few years back for use with such technology, though when they were initially released for use with digital cameras etc they tended to have lower capacities from 32-128kb. Eventually one and two gigabyte cards were unveiled, though these were rather costly and performance would vary with certain devices. This meant that only a limited number of photos could be stored on the camera, which became more of a serious problem as technology developed and cameras started to take pictures with more and more pixels – using a ten mega pixel camera you’d only be able to take a couple of photos before running out of space. Video modes created further problems. Likewise PDA’s developed the ability to run 3D games and play videos, while people who used MP3 players began to expect to fit entire libraries of music on their portable device.

With the advent of SDHC cards however, storage went up to an extra 30 gigabytes, more than enough to take hundreds and hundreds of photos on just one memory card and hours worth of footage. With Micro SDHC cards even the size was improved, with these cards fitting on a small coin. As though that wasn’t enough, the price also dropped significantly making even the larger cards very affordable. However just as SDHC cards stepped up their game, so too did the cameras and other gadgets. Today many phones and gadgets come with large amounts of memory built in – some almost as much as a low-end computer – so if your gadget offers that as standard, why would you need an SDHC?

Firstly, flash memory (the type used by SDHC cards) is non-volatile, meaning that it won’t get ‘wiped’ as it doesn’t rely on an internal battery etc. This is still not the case with many PDAs, cameras and phones which require a small internal battery (in addition to the main battery pack) in order to keep data stored – meaning that if you leave your phone uncharged for a long time you will lose all of the internal memory.

Furthermore, SDHC cards offer far more compatibility and don’t require installation. This means that you can share your photos or music with a friend without needing wires or plugs. Finally, SDHC cards are far more portable, meaning you don’t have to carry a bulky camera or PDA everywhere you want to take your data. And anyway, why settle for 30 gigabytes in-built when you can double that with a memory card? In fact the cards are so small that you could very easily carry twenty of them and have almost endless capacity.

So yes, SDHC cards and their variations are still very much practical and necessary in today’s technological market and will likely continue to be so. More interesting though is upcoming SDXC card which promises up to a terabyte of data, significantly stepping the game up again.

SD Cards were great but then we got higher capacity cards called SHDC, a new and improved version is planned but till then SDHC cards are the favorites.

Digital Scanners and Scanning Technology

admin — Thu, 08 Jul 2010 02:17:08 +0000

A digital scanner is a computer device that is employed to scan written documents & photographs to feed into a electronic computer in the form of data format such as JPEG, GIF, PNG, and so on. After scanning the papers or photograph, it can then be printed or transmitted via electronic mail or telefaxed to others.

Documents may as well be changed to different data formats like text or doc data format after doing OCR. Digital scanners are commonly employed by many to create replicates of photographs and documents. They are likewise employed by professionals.

Across the years, the applied science behind scanners has experienced a lot of new developments and gains. Nevertheless, the size of electronic scanners has stayed the same to suit the basic size papers.

Nonetheless, their height has decreased step by step. Today, nearly all mid-size digital scanners obtainable in the market measure out about ten by fifteen by three inches in proportions & weight nearly four pounds. Digital scanners employed by professional printers are a great deal bulkier and have additional characteristics for automating the scanning work.

Virtually all digital scanners acquirable in the market have equal characteristics. Nevertheless, depending upon the cost, the quality of the scans is distinguishable. Advanced digital scanners tend to create clear scans whilst the scanning quality of inferior scanners may be a little down.

The quality and fastness of scanning may be adapted utilizing the software package that goes with the scanners. It’s likewise possible to correct the colors & do image processing later on the photographs or documents.

Almost all digital scanners come with a software package compact disc that has device drivers to use the digital scanner & extra supportive software packages like picture editing tools, photograph album software and OCR software. These packages may as well be bought individually.

If you’re thinking of purchasing a scanner, it’s best to look at investing in an all-in-one. An all-in-one integrates a digital scanner on either a ink-jet printer or a laser printer. All-in-ones are more affordable and are more beneficial than standalone digital scanners or printers. As a matter of fact, an all-in-one may also be employed as a xerox machine without even plugging in to a PC.

When you’re purchasing a digital scanner, decide wisely. Ascertain that it conforms to all your requisites. The worthiest digital scanner brands in the market include Canon, Epson, H.P. & Dell. You’ll be able to find scanners at internet stores at much more affordable costs. Nonetheless, you’ve to wait for a couple of days to get your digital scanner in mail service. When purchasing online, always purchase from reputed web sites like TigerDirect or NewEgg. In addition, study user critiques for drawing a better estimate about the digital scanner before purchasing.
