A toner cartridge is a cartridge that contains physical print media materials for a modern laser printer. Instead of an ink like the printer with an inkjet principle. A toner cartridge contains toner powder with which text and graphics as well as vector graphics are generated on a page by an electronically charged and heated printing process. Simply put, the text and graphics are almost burned onto the paper!
Although the toner cartridge is a straightforward and simple part of a printer, the design of new laser printers and toner cartridges has created major problems with cartridges for more sustainable and long-term use and the possibility of refilling. There is a conflict among printer manufacturers some of whom are charging so much for cartridges that printers are becoming single-use devices. This can lead to excessive waste and costs for the customer.
