A PostScript Cartridge for an HP LaserJet printer #VintageComputing #LaserJet #HP

Pagetable recently dissected and dumped the Level 2 “Plus” version of HP’s PostScript cartridge series. This time, they will look at the earlier Level 1 “PostScript Cartridge”.

There are two cartridges for the HP LaserJet series that add Adobe PostScript support. They differ in the PostScript Level:

Year Name Description
1991 HP LaserJet PostScript Cartridge PostScript Level 1
1991 HP LaserJet III PostScript Cartridge Plus PostScript Level 2

Such cartridges were available to plug into early HP LaserJet printers to provide fonts or capabilities (like this one).

The front says

Inside is the very same board as used by the later “Plus” cartridge, except that it is fitted with only three instead of four ROM chips.
