On a Linux computer with a printing subsystem, it would be as simple as printing to a file. On the Itablet -- ugh. I have tested QuickScript on my old non-networked PS LaserJet (with a Bluetooth module), but haven't yet managed to get a connection right. I have a colour LaserJet with Ethernet AP, but it's been mothballed, so testing that won't be easy. Penguinbait ported Cups to his KDE port, so maybe you could try that?
