LaserJet 5MP

The HP LaserJet 5MP arrived in the mid-1990s as the PostScript-savvy member of HP's compact 5P desktop family. Built for personal desks and Mac-heavy offices, it packed genuine Adobe PostScript into a small monochrome laser — a combination that made it a favorite for desktop publishing and proofing work in its day.

Keeping one running today takes the HP 03A cartridge, part number C3903A. We stock both compatible 03A toner and genuine OEM C3903A cartridges for the 5MP, so you can match print quality expectations to your budget.
