print to HP printer #6

Test if the v1 hardware can actually be used for printing. We can't reasonably claim to have integrated with the parport stack without having completed this experiment successfully.

I happen to have an old HP Deskjet 1220C printer that has both 36-pin parallel and USB interfaces.

Built lp module, set up CUPS for the deskjet. Test job: cups thinks it prints, but printer doesn't seem to get it.

Oh, I forgot that I had disconnected the control lines on the adapter I was testing. Putting those back, I was able to print a tabloid schematic of this project to the printer over parallel.
