Laser vs Inkjet vs Thermal Printer: What's the Difference?

Laser printers use a laser, drum, and toner fused with heat to print fast, sharp pages in volume. Inkjet printers spray liquid ink through tiny nozzles and excel at color photos. Thermal printers use heat on special paper or a ribbon and are common for receipts and labels.

Laser bakes powder, inkjet sprays liquid, thermal uses heat alone.

Exam tip

Know the laser imaging process order: processing, charging, exposing, developing, transferring, fusing, cleaning. Smudging that wipes off points to the fuser; ghost images point to the drum or cleaning.
