The HP LaserJet III

I was just given two of these (October, 2011) by a nice fellow.

The LaserJet III is HP Model number 33449. It sold for $2400 in 1990. No postscript built in. Like the Apple Laserwrite II, these are 300 dpi laser printers, use the 92295A toner cartridge, and like the Apple Laserwriter II, has the Canon "SX Engine" inside.

Uses the HP PCL 5 printer language. This was essentially HP's response to Postscript.

A genuine HP LaserJet 92295A cartridge is said to be good for 4000 pages of normal text. HP no longer makes the 92295A cartridge, (they discontinued it in November of 2007), so you are pretty much stuck with remanufactured cartridges, which vary wildly in quality and performance.

Control Panel

There are two lights (ready and manual), a display, and 8 buttons.

Service Mode

Hold down online, continue, and enter while powering on the printer. This yields a blank display. Type continue, then enter, and you are in service mode. Pressing Menu will display the page count (which will also be printed on the test mode sheet). My printer shows 34360.

Resources

I have not found any manuals online.
You should look at the Apple LaserWriter II pages I have, which reference the apple manuals. Since both printers use the Canon SX engine, the Apple repair manuals are quite relevant.
