Looking into it now.. I downloaded the xprint debian source package. A quick initial look indicates that this possibly has to built together with the xserver (I mean it's part of the xserver source and maybe it won't work with anything else than the one it's built with) .. I'm not certain. The xserver on the NIT is xserver-xomap, what I can't tell from its Description is if it's based on XFree86 or xorg. I'm almost certain however that someone else here on ITT is more familiar with xserver-xomap than I am, because I remember from far back that someone fiddled with recompiling it (well, maybe that discussion took place on the maemo-developers' list actually).

Anyway, I'll give it a go (the standard Debian xprint) just to see what happens.
