Drop On Demand Printers
by: Bill Smith
Most HP and Epson printers are drop on demand printers. They use electrical pulses to fulfill requests for ink. The ink is expelled out of the print head by a bubble which forms as a reaction to being heated. Once the ink is propelled out of the cartridge, the bubble cools, contracts, and forms a vacuum of sorts, which pulls more ink into the nozzle.
HP DeskJets and BubbleJets are popular examples of printers that use this technology.
Epson printers work on the same principal with the exception of a minor twist ? they use a transducer to produce the droplets in what is referred to as piezoelectric DOD.
So what about the ink ? does it matter what kind you buy as a replacement?
The answer is yes, it does matter.
The ingredients that go into ink play a huge role in the quality of your printouts. All ink manufactures work to strike the delicate balance between print quality, time it takes to dry, and nozzle performance. As you might have guessed, as the print quality improves, the dry time increases.
Manufacturers have to be careful that the ink does not dry too quickly ? there is the danger that it will actually dry on the nozzle. This can ruin your print head, definitely clogging up your nozzle, and reducing the print quality.

Optimize Your Computer For Peak Performance
by: Lanard Perry
Is your computer running slower than ever? Does it crash a lot?
If so it might be because advertisers have loaded it up with Spy and Adaware without your knowledge.
"Spyware" is a common term for files that are installed on your system that allow companies to monitor your Internet activity.
"Adaware" is software that will show you pop up ads over and over. These files can be extremely dangerous to your PC and could cause major problems.
They track the websites you visit, items that you buy online, the emails you send and your Instant Message dialogues. In a worst case scenario they can even record your credit card number, personal identification numbers, and all of your passwords.
I know all of this because I learned the hard way. Fortunately, I never had any personal data stolen, at least that I?m aware of. But every now and then, when least expected,...
