LaserJet 5SI MX

The 5Si MX bundled HP's LaserJet 5Si workgroup printer with the options offices actually wanted — networking and expanded capability — in one late-90s package. The result was the same dependable A3 monochrome engine, ready to drop straight into a busy department.

One cartridge serves it: HP 09A, part C3909A. We carry compatible 09A toner and genuine OEM C3909A cartridges for the MX.
