Solid ink printers, also known as phase-change printers, are a type of thermal transfer printer.They use solid sticks of CMYK-coloured ink, similar in consistency to candle wax, which are melted and fed into a piezo crystal operated print-head.
The printhead sprays the ink on a rotating, oil coated drum.
The paper then passes over the print drum, at which time the image is immediately transferred, or transfixed, to the page.
Solid ink printers are most commonly used as colour office printers, and are excellent at printing on transparencies and other non-porous media.Solid ink printers can produce excellent results. Acquisition and operating costs are similar to laser printers. Drawbacks of the technology include high energy consumption and long warm-up times from a cold state. Also, some users complain that the resulting prints are difficult to write on, as the wax tends to repel inks from pens, and are difficult to feed through automatic document feeders, but these traits have been significantly reduced in later models.
In addition, this type of printer is only available from one manufacturer, Xerox, manufactured as part of their Xerox Phaser office printer line.
In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.
In the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix systems that could mix text and graphics but produced relatively low-quality output.The plotter was used for those requiring high quality line art like blueprints.Źródło: https://en.wikipedia.org/wiki/Printer_(computing).
