   en.wikipedia.org/wiki/Toner_cartridge

   Toner cartridges contain toner powder, a fine, dry mixture of plastic particles, carbon, and black or other coloring agents that make the actual image on the paper. The toner is transferred to paper via an electrostatically charged drum unit, and fused onto the paper by heated rollers during the printing process. It will not stain like ink ...

5. Photocopier - Wikipedia

   The mechanical tolerances of the toner and paper feed mechanisms cause banding, which can reveal information about the individual device's mechanical properties. It is often possible to identify the manufacturer and brand, and, in some cases, the individual printer can be identified from a set of known printers by comparing their outputs. [15]

6. Ink cartridge - Wikipedia

   en.wikipedia.org/wiki/Ink_cartridge

   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.

7. Laser printing - Wikipedia

   en.wikipedia.org/wiki/Laser_printing

   Toner is fused onto paper with heat and pressure. The paper passes through rollers in the fuser assembly, where temperatures up to 427 °C (801 °F) and pressure are used to permanently bond the toner to the paper. One roller is usually a hollow tube (heat roller) and the other is a rubber-backed roller (pressure roller).
