Toner And Printer: Toner is a powder mixture used in laser printers and photocopiers to form the printed text and images on paper, in general through a toner cartridge. Printers rely on ink or toner to produce images on paper or other media. The biggest difference between ink and toner is probably the fact that each of these works with a different type of printer. Inkjet printers rely on ink while laser printers rely on toner, but the differences don't stop there. While the ink is still relatively expensive to refill or replace, toner powder is much more affordable over time. This also makes it more efficient and less wasteful because inkjet cartridges often force users to refill or replace them before they've been completely depleted.
