Heyy. I just got an airport express set up in my dorm and it's working except that my powerbook can't print to the shared printer. The printer is a HP Deskjet D4160. The airport express clearly sees that it's a HP Deskjet 4100 series because it says so and when I go to add the printer it finds the right drivers and everything. However, when I try to add the printer I keep getting the error "An error occurred while trying to add this selected printer. Error:-9672" Any ideas as to why this is happening? It's the exact same setup and same driver when connected by USB and the printer works great. I tried gimp print drivers too but there aren't any for the D4160. Even stranger, the Bonjour setup wizard on my XP laptop found the printer, added it, and printed to it without any problems at all. it's only on the mac where it's not working.
