The company developed the Micro Piezo inkjet technology, which used a piezoelectric crystal in each nozzle and did not heat the ink at the print head while spraying it onto the page, and released the Epson MJ-500 inkjet cartridge for the Epson Stylus 800 printer in March 1993.
Inkjet printers also suffer from 'dye wastage' as the ink cartridges are prone to drying up with low usage (without 'heavy use', the cartridge nozzles can become clogged with dried ink). Dye-sublimation media packs, which include both ribbon and paper, are rated for an exact number of prints which yields a fixed cost per print.

Some tank-on-carriage printers such as Epson use a fold-over clamping system over the tank to secure it in place on the print carriage. This clamp blocks the path of tubing from a continuous flow system feeding the tanks, and the print carriage may need to be modified by removing the clamp, cutting holes in the clamp, or installing a retrofit ...
Some manufacturers incorporate the printer's head into the cartridge (examples include HP, Dell, and Lexmark), while others such as Epson keep the print head a part of the printer itself. In 2014, Epson introduced a range of printers that use refillable ink tanks. Epson's EcoTank printers offer a refillable ink tank system, which can ...
There are several types of 3D printer extruders. A Bowden extruder is a type of extruder that pushes filament through a long and flexible PTFE (Teflon) tube to the hot end. [1] An alternative type of extruder which is also widely used in filament 3D printers is the direct-drive extruder, which sits closer to the extruder hot end.
Beyond this point the nozzle diameter becomes the biggest diameter and starts to incur increasing drag. Nozzles are thus limited to the installation size and the loss in thrust incurred is a trade off with other considerations such as lower drag, less weight. Examples are the F-16 at Mach 2.0 [21] and the XB-70 at Mach 3.0. [22]
