I thought about the printer/driver issue and that may make this option too much of a PIA to do.
I would still like to heartily encourage you to experiment with the rPi solution (in addition to the easy Ubuntu solution) because I've been thinking it would be pretty great to be able to post up a rPi SD card image that would give people the ability to:
* Download rPi SD image and burn to card
* Pop it into a rPi
* Plug in a display, mouse, and printer
* Power on and use mouse to start printing wallets, never having gone online expect to retrieve the rPi image.
The only hangup I see here is:
* sufficient printer drivers
* would be great to plug in mouse, printer, and keyboard (esp. for supplying BIP38 keywords) but that would require a USB hub. Maybe not a big deal, but I love the idea of something that's so self-contained.
