The printer was originally directly connected to my PC and it worked fine from my PC and the other PC on my small network. Both PCs are running Windows (mine is XP and the 9. I got the printer server so my PC wouldn't have to be on all the time. So I know that the printer and cabling work and work with this PC. When I boot my XP PC with Knoppix, however, and try to print I can see (via the lights on my router and the printer server) that something gets to the server but nothing gets sent to the printer.
