You can’t just buy any printer cartridge as it might not work in your printer. The printer you own or plan to buy is either a laser printer or an inkjet printer. For the former, your replacement cartridges are laser toner cartridges; the for the latter, inkjet cartridges. Each uses a different kind of printer cartridge. Simply put, laser toner cartridges are containers for a dry substance that fuses on the surface of any kind of paper. Laser printers, because they can print thousands of pages fast, save both time and money via fewer cartridges bought over time. If you don’t need massive quantities of documents to print out regularly, as some offices do, then inkjet printers are fine for you. One way to cut down on costs when you replace laser toner cartridges and inkjet cartridges is to use remanufactured cartridges.
