LaserJet is the brand name used by the American computer company Hewlett-Packard (HP) for their line of xerography (DEP) laser printers.

LaserJets employ electro-photographic laser marking engines sourced from the Japanese company Canon. Most early printers used internal firmware, controllers, associated software, and drivers developed internally by HP and were considered their "value add" to the standard printer engines. Beginning with the LaserJet 4000, HP has nearly completely outsourced this work to Oak Technology, now Zoran, among many other suppliers.
