  • The Hewlett Packard LaserJet IIP popularized the desktop personal laser printer. Released in 1989, the model was among the very first laserjets available for less than $1,000. Deemed a "milestone" printer by the New York Times, the paper touted the unit's light weight (the IIP weighed *just* 25 pounds). Here's what made the IIP tick.

    The design was beige and boxy.

  • The IIP held a nominal amount of paper in its default configuration. Printing envelopes, meanwhile, required removing the main paper source.

  • The IIP's power switch was on its right side, along with an expansion slot visible toward the case's top side.

    I remember having one of these; nice printer. you could get a 3rd party PostScript cartridge for it IIRC.

  • Transfer roller

    The part you labeled a fuser roller, sequence no. 10, is actually the transfer roller. Paper runs between it and the drum in the toner cartridge, and a strong charge through the conductive foam rubber of the transfer roller pulls toner image off the drum and onto the paper between them.

  • Canon parts

    On sequence no. 18, you point out that the main drive motor is made by Canon. In fact, the entire print engine is from Canon, as with most HP LaserJets. HP adds their own controlling electronics and operation panel, but the guts are pure Canon. The label on the motor includes a part number, RH7-1094. That's the alpha-numeric pattern of Canon parts, and HP also uses those numbers for those parts they don't specifically design for their own machines.

    Hey, I've still got a IIp, and it's still working fine.

    And I've got the lower tray assembly and maxxed out memory.

      @rag@... My school had one of these locked away in a closet, and I wanted to bring it home, but they threw it away before I could get it. Oh well, at least I managed to get an LJ4. They just don't make them like they used to.
