All printer suppliers produce their own type of ink cartridges. Cartridges for different printers are often incompatible — either physically or electrically. 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.
Released drops either fall vertically without any trajectory manipulation or require special fire timing when projected horizontally from a rotary printhead spinning at 121 RPM to form characters (Howtek color printer 1986). Commercial printheads can have a single nozzle (Solidscape) or thousands of nozzles (HP) and many other variations in ...
The principle is the same for practically all card printers: the plastic card is passed through a thermal print head at the same time as a color ribbon. The color from the ribbon is transferred onto the card through the heat given out from the print head. The standard performance for card printing is 300 dpi (300 dots per inch, equivalent to 11 ...
On the other hand, inkjet printer designs which use a disposable printhead usually cost significantly more per page than printers using permanent heads. [ citation needed ] By contrast, laser printers do not have printheads to clog or replace frequently, and usually can produce many more pages between maintenance intervals.
Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [2] [3] and typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper. They were also known as serial dot matrix printers. [4]
More expensive, business-grade printers use progressively larger ink tanks on the printhead, but as the platen width and speed of the printer increases it eventually becomes impractical to have the tanks integrated with the printheads due to the high mass and inertia the liquid volume adds to the printheads and the reduced accuracy of printing ...
The MX-80 is a serial dot matrix printer introduced by Seiko Epson in 1980. The MX-80 is capable of printing a maximum of 132 columns per line, while its 9-pin printhead was the first disposable, user-serviceable printhead on the market.
Unlike some inkjet printers where the cartridge includes the print head, the printhead in these printers is fixed. Over time, parts of the printhead may become permanently clogged, resulting in unsightly streaks, but there are printhead and drum cleaning cycles and jet-substitution options which can resolve most printing issues.
