A HP color laser printer with its cartridge drawer open showing the four toner cartridges inside. Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black . While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors.
Laser line levels are used in surveying and construction. Lasers are also used for guidance for aircraft. Extensively in both consumer and industrial imaging equipment. In laser printers: gas and diode lasers play a key role in manufacturing high resolution printing plates and in image scanning equipment.
Lasers are used in fiber-optic and free-space optical communications, optical disc drives, laser printers, barcode scanners, semiconductor chip manufacturing (photolithography, etching), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and ...
This Harvard-made 3D printer can create complex metallic objects other printers can't. See, instead of spitting out one layer over another, the machine was designed to ooze out metal that ...
Printer steganography is a type of steganography – "hiding data within data" [30] – produced by color printers, including Brother, Canon, Dell, Epson, HP, IBM, Konica Minolta, Kyocera, Lanier, Lexmark, Ricoh, Toshiba and Xerox [31] brand color laser printers, where tiny yellow dots are added to each page. The dots are barely visible and ...

[1] For example, in a laser printer this would consist of the laser and drum and the mechanical paper feeds. Memory to process input and build up the image of a page. The printer may have its own memory or may use the host computer's memory. A page description language (PDL), with commands which tell the printer how to format the page.
Toner is a powder mixture used in laser printers and photocopiers to form the text and images on paper, in general through a toner cartridge. Mostly granulated plastic, early mixtures added only carbon powder and iron oxide ; now there are mixtures that contain polypropylene , fumed silica , and various minerals for triboelectrification .
