Killed my HP printer

Well I managed to drop my HP inkjet from the top of my computer to the floor.· Definitely terminal.· A tiny little tab that retains the slidding print head to motor belt was broken off - no more left and right.· Otherwise fine.
If anyone is interested in the cannabalized print head carrier, I saved that as Mr. Jon Williams has demonstrated that you can attach it to a BOE and get it to print messages as it rolled.
I believe you have to use the SX-28 to drive the printer head.· Mine takes the #27 ad #28 inkjet cartriges.·
It is yours for the cost of postage from here [noparse][[/noparse]Taiwan].
Is there any way to exploit the USB interface.· It has very odd voltages +15 and +34.
I just bought a Canon iP1000 because the HP·ink has been too expensive.· I may not be getting a better deal but someone else can share the exploitation.· Japan's economy has been flatter than the USAs.· I must say it makes a lot more noise.

Applications Engineer, Parallax
I cannibalized the unit because there are no replacement parts here.
I thought the electronics might be of use, but there are only two tiny, complex boards.
About the only real benefit I gained from the disassembly is to see how they approach modern EMI problems {they have a sheet metal shield with cooling holes covering quite a bit of one board and an EMI shield on one larger electrolitic capacitor}.
From what I understand, Parallax sells a package that holds that head and is adapted to mount on the BOE. Over all that is a much easier way to go.
I certainly wouldn't recommend wrecking a perfectly good printer to do the reverse-engineering. As I mentioned above, the power supply is quite unusual and I don't see how it might fit into a battery operation.
