Is there any technical manual for the 82240B printer ?
I mean, about commands, IR signal format, etc.

Maybe the HP82240B Technical Interfacing Guide PDF is what you're looking for? Other than that, a scan of the owner's manual is on the MoHPC CD set/DVD.

Are there schematics/internal pics/pcb layouts available? It seems I had seen some at one time, but can't find them now. TomC

Also, there was a detailed article in the HP Journal which is on the Museum disks. It may be available online here too. TomC

There should be reverse-engineered schematics for both the 82240A and 82240B on the HPCC CD-ROM. They're pretty simple inside, an 8048 microcontroller, the IR receiver chip, and a driver chip for the printhead/motor. From what I remember, if you want to take one apart, there are 2 case screws (4 under the feet, 2 in the battery compartment). |
