By using control codes it was possible to change the printed text style using font patterns stored in permanent ROM in the printer. Instead the first LaserJet was primarily intended for use as a high-speed professional replacement for text-only daisy-wheel impact printers. It took approximately two minutes for the first page to print out. This rendered the LaserJet nearly useless for direct graphical image printing, with it only capable of printing a low-resolution 75-dpi image about 1 inch square before running out of memory. It was an 8ppm printer that sold for $3495.ĭue to the high cost of memory, the first LaserJet only had 128 kilobytes of memory, and a portion of that was reserved for use by the print engine.
The first mass market laser printer for IBM Compatible personal computers was introduced in 1984 by HP as the LaserJet. Beginning with the LaserJet 4000, HP has nearly completely outsourced this work to Oak Technology, now Zoran, among many other suppliers. 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. LaserJets employ electro-photographic laser marking engines sourced from the Japanese company Canon. LaserJet is the brand name used by the American computer company Hewlett-Packard (HP) for their line of xerography (DEP) laser printers.
