There are differences between laser printer and ink cartridges. You can’t just purchase any cartridge and expect it to be compatible with your printer. You have to know what kind of printer you have. A laser printer contains a powdery, carbon-based substance rather than ink, which is chemically fused to the paper. When compared side to side, laser printers cost a bit more than inkjet printers; so with toner cartridges and inkjet cartridges. But in the long haul, the former saves you money. Laser printers can rapidly print hundreds of pages and are compatible with any paper. Inkjet printers and their inkjet cartridges are cheaper upfront, and if you don’t need massive and quick printing, their quality is more than enough. You might want to investigate alternatives to buying ink and toner cartridges that bear the printer manufacturer’s brand, as these can be costly over time. One alternative is to buy remanufactured cartridges.
