The laser printer market has many players, but the most prominent are Hewlett-Packard, Tektronix, and Lexmark. Laser printers do not use inks per se. They use a toner, much like your average photocopy machine. Images are generally created as a series of dots, but in a laser printer the dots are minute particles of toner, with densities usually up to 600x600 dpi. Toner cartridges are usually affordable, last for several thousand pages, and don't need to be replaced frequently under normal usage.
Laser printers offer an extremely fast and crisp image replication system.
Laser printers are usually monochrome devices, but as with most mono technologies, laser printing can be adapted to color. As we ve seen, virtually any color can be made from a combination of cyan, magenta, yellow, and black, and a color laser produces color output by performing four passes through the electro-photographic process. Micro Dry technology can produce images up to 2400x2400 dpi for both monochrome text and photo quality color output. Micro Dry inks come in spooled cartridges that appear similar to impact dot matrix ribbons, but are much different in use. Alps Micro Dry technology uses a true CMYK four-color process, laying down completely dry resins that do not absorb into the paper.
