I've done a tiny bit with Samba, but have no experience with networked printers. There's an HP Business Inkjet 2200 in our office. I'm trying to print to it today, but while I don't see any errors, nothing's printing either. When I go to System -> Administration -> Printing, I think I see the printer I need, but the Device URl is listed as file:///dev/null. I click the "Change . . ." button, look under "Network Printer," and see HP Business Inkjet 2200. That shows a listing of IPP Printer and next to "Host" it lists 192.168.107.254:631. However, a coworker shows a completely different internal IP address for the printer I'm trying to use. I'm really stumped and don't know what to check from here.
