Drop On Demand Printers

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.

When you buy remanufactured ink cartridges be sure to pay close attention to the kind of ink that was used to refill the cartridge. There are cheap substitutes on the market which have a shorter life span and print poorly.
