Yes.

Toner for a printer is supplied in a toner cartridge. It is generally made of plastic and pigment, supplied with an electrical charge, which is essential to its function. When printing, the drum starts off with a positive charge, and then the printer uses a beam to discharge various spots on the surface of the drum, which creates an electrostatic image onto the surface. Finally, the toner coats the surface of the drum, and the paper picks up the image.

Toner cartridges are used in printers. They are what transfer words onto paper. They melt a fine black powder made of plastic particles, carbon, and coloring agents onto it using precision rollers.

High-yield toner cartridges have more toner in them than normal toner cartridges. A high-yield toner cartridge can reduce the cost of toner per page by half. Much of the cost of toner cartridges is related to the housing not the toner itself.
