How To Buy The Best External Hard Drives
The technology moves fast and leaves us with gizmos and gadgets, which are more and more functional, and at the same time smaller than we have ever thought they could be. What’s more, the technology also adds these gadgets the mobility so that they can be used as and when required, wherever they are required.
One such device following the suit is your hard drive and with the introduction of an external hard drive, what you get is data storage and security with added mobility. These are the hard disk drives (HDD) that are actually placed outside of the computer system. With the data security, mobility and an option to remove this drive, you can take all your data with you.
The external hard drives or HDD are built to perform externally. This means that the HDD comes with built-in cables that allow you to interface with your computer system. While the conventional HDD connectors would use SCSI or SATA cables that connect to a type of HDD connector inside your computer, the new variants of this external HDD uses an innovative and simple method of connecting via the USB or the FireWire.
Most of the external HDD come with the ability to backup the data from your PC. The only limiting factor for the HDD as on today is the cost, as they tend to be more expensive as compared to the internal HDD with the same capacity.
These devices are purely meant for data storage and backup but how much data can it store? There are many options available for you as far as the data storage capability of this device is concerned. Usually, the most common drives are of the same size as a normal hard disk inside your computer.
However, there are many other storage disks that are available at this point of time, with as much as 1000GB of data storage capability. With this amazing speed of the technology, it won’t be too long before we move into true Terabyte reign. These huge storage capacities are responsible for this device rapid popularity as popular form of computer backup for the computer users.
The reasons to opt for this particular device are many, for instance, it provides the user with convenience and simplicity of use. This is so as most of the computer owners are not comfortable opening the cases of their computer and installing additional hardware. This is eliminated when you simply opt for this device rather than an internal HDD.
With this particular device there is no need to open the PC case, instead you simply need to plug it in and go. Another advantage of the external HDD is its portability and mobility. Compared to the internal drives, external drives can be moved from PC to PC in a matter of minutes, simply by unplugging them from one and plugging them into another.
Thus the external hard drives are often used in the business world, especially by traveling employees. Traveling employees can instantly sync up the data on an external hard drive with that on their desktop or laptop PC, and then easily carry that data anywhere in the world. This also might eliminate the need of carrying the laptop.

Buying a Photo Printer
As more and more of us have turned to digital photography there has been a huge surge in demand for printers that can deliver photo print quality reproduction that we have been used to with a developer shop. With the development of improved technology delivering a wider range of printing options you will find a bedazzling array of photo quality printers to choose from so here we shall give you some sound advice as to what you should be looking for in a new photo printer.
Compact Photo Printers
These are portable and will connect directly to your digital camera or PC as well as having a slot for the memory card to be directly inserted into them and allow download and printing of the photos directly.
A drawback is that they are limited in what they can produce. The size of the photo print created is usually a lot smaller than that of a desktop printer but they do print photo quality prints faster.
Check the compatibility between the photo printer and your camera to ensure they will operate together properly.
Desktop Photo Printers
These printers are capable of stand alone operation or work in conjunction with your computer. They tend to provide a wider range of print size options as well as they are larger and tend to offer more paper handling options than their compact brothers. You will find that they are more expensive but for the extra you get higher printing resolution and a faster operation speed than a regular desktop printer. Indeed, it is not unusual to find that they have all the functional capabilities of a regular desktop printer.
What is DPI?
DPI or dots-per-inch is the measure of a printers resolution capability with a higher dpi meaning that there are more dots, smaller in size and giving an image that is sharper as it is more difficult to distinguish between the individual dots than with a printer that has a lower dpi. For photo print quality you will be looking for a dpi of 600 while typically a printer will offer a dpi of anything between 300 and 3500 dpi. Aside from dpi, the other factor you need to consider in producing good quality reproduction prints is the quality of the paper that you use and the number of colors the printer is using.
Color Management
Usually you will see a photo printer using three to six color combinations to reproduce color prints. The more colors that the printer is using the better the finished article as you tend to get a blurring or fogging of darker colors if you use three colors only. More color cartridges however means more expense as a rule, so keep an eye on the cost of these consumables when you are looking at buying a photo printer.
Printer Type
You have a general choice from two types of printer that are differentiated by how they apply the ink to the paper. Laser printers use heat to force the ink through the print head and onto the paper but they produce dots of differing sizes which in turn leads to a less sharp image being reproduced. An ink jet printer will spray the ink onto the paper in a gradual series of layers that results in a uniform dot size and a much sharper image being reproduced. You will tend to find that the better quality photo printers use ink jet technology though laser printers are improving a great deal.

Diagnosing and Solving Common Printer Problems
Any business owner or manager knows how important printers are to success. When the printers are down productivity suffers, and even the most robust business can grind to a halt. While many large companies can afford to hire professionals to troubleshoot and maintain the printers in the office, many smaller business owners find themselves wearing the hat of the printer repairman. Knowing how to diagnose and solve common printer problems can save those business owners lots of time and money, while at the same time keeping the business productive and profitable.
While there are many different kinds of printers, made by a host of printer manufacturers and wearing a number of name and model badges, most printer problems break down into a short list of categories. Understanding what these breakdowns mean, and learning to diagnose the parts most likely to cause those problems, is a big part of successful printer troubleshooting.
Problem 1 Paper Jams
Paper jams are perhaps the most common of all printer complaints, and they can also be one of the most difficult to diagnose. When a printer begins suffering from persistent paper jams, one of the most important steps is to look for a trouble code on the printer. If such a code is present, refer to the manual that shipped with the printer, or the manufacturers website, for information on how to clear the jam and prevent it from recurring.
Paper jams in laser printers are often the result of worn out rollers in the paper trays, so it is important to check those rollers when those jams occur on a regular basis. Most modern printers make it fairly easy for users to change the rollers, and it is a good idea for printer owners to keep a number of extra rollers on hand. When changing worn rollers, be sure to refer to the printers user manual, or instructions on the manufacturers website.
Problem 2 Ink Rubbing Off
Sometimes printer users will discover to their dismay that the ink rubs off the page easily, and this problem can easily result in a stack of unusable paper and hours of wasted time. When the ink rubs off the pages easily the most likely culprit is a defective or worn out fuser. Again, most modern laser printers make it fairly easy for printer owners to swap out a fuser cartridge, but it is still important to carefully follow the directions that came with the replacement cartridge. As with rollers, keeping an extra fuser cartridge on hand for each printer model can save a great deal of time and hassle.
Problem 3 Ink Spots and Inferior Printouts
Spots or other imperfections on the printouts can also be the result of a worn out fuser cartridge, so it is important to check the fuser when this problem occurs. If changing the fuser does not solve the problem it may be that the printer simply needs a good cleaning. Ink from the toner cartridge can often leak into the interior of the printer, causing spotting on the pages. Cleaning the printer with a specially designed cleaning cloth can often put the problem to rest.
If the problem continues it may be time to change the toner cartridge. As toner cartridges age they can begin to leak and cause other problems. If spotting is seen on the pages it is important to look carefully underneath the toner cartridge for loose ink and to remove any ink that is found. If ink is continually found inside the printer the toner cartridge is probably leaking and should be replaced at once.
Problem 4 Light Printouts
This is perhaps the easiest to solve of all printer problems, and one of the most common. If the printouts begin to appear light, the most likely cause is a worn out toner cartridge and replacing the toner cartridge should resolve the issue. If the toners seem to wear out too quickly, it may be a good idea to look into changing brands or suppliers. Each toner cartridge should come with an estimated life, and it is important to monitor actual usage to ensure quality service when buying printer consumables.

What’s The Best Computer and Why
You might be surprised at the answer. Through the years I have been asked this question many times. People understandably would like to know the answer before spending their money. Many think that the only answer is in the big names that they have heard. And it’s no wonder these same companies have spent millions promoting their names.
What would make up the best computer? In my opinion it should have a minimum of these qualities. Be reliable, easy to upgrade, parts readily available, easy to work on and long lasting. The only one that meets all these requirements is the generic computer that is built by you or a computer dealer.
Computers are different than almost any other product. You probably wouldn’t want to build your own car for example. But early on manufacturers began supplying Cases motherboards and the rest of the parts to build a computer. So an industry sprang up and some bigger companies plus local dealers built computer to your specifications. These had many advantages the main one being that you could find parts anywhere at reasonable prices.
What sometimes happens for example is say a motherboard goes bad. Because of the way the major manufacturers computer is built a generic or another manufacturers won’t fit this has nothing to do with the electronics it’s a mechanical thing it physically won’t fit or screw holes won’t line up. Now the generic motherboard might run $80.00 to $100.00 while the major manufacturers could be $250.00 to $300.00 or more. After paying that much for parts plus the labor many are thrown in the junk rather than fixing. The same goes for power supplies. Many times the off the shelf power supplies won’t work in these computers. They will make you pay dearly and many times the power supply will need to be special ordered from the major manufacturer.
In other respects I think the computers are about equal. Taking into account that almost all of the parts in the major Brands are made by the same companies that make the generic parts. In selecting your generic computer do some research in is quality of product. What desktop computers will last, and which ones would not? What are the highest quality components? Does the company offering you desktop computer deals provide good warranties? Finding a cheap computer is less exciting when you find out that that computer is a lemon. The fact is that desktop computer deals are not real deals if you get a machine that doesn’t last out of them.
Our discussion has only covered desktops and the pc. The apple computer is a different story and isn’t covered here. Laptops are another story also and I will cover these in another article. If you were to ask almost any computer dealer I think most would agree with what I have said.
Lately the majors have started to make their computers more compatible. Maybe they have begun to see the light. In the mean time I hope you will consider buying your computer from your local dealer or repair shop.
