A printer toner is a simple powder used to refill printer ink. It consists of positively and negatively charged particles, which serves to control the color and intensity of the marks made on the paper. Toners are known to produce more long-lasting prints for inkjet papers. Toners are available in both black and colored ink. Like ink cartridges, toners also come in different types like OEM, remanufactured, generic or compatible as well as branded.

Either you are buying your printer toner from retail supplier or online vendor make sure to check for your printer’s compatibility. A wrong toner cartridge can ruin the printer completely so be aware before buying a toner for your printer.
