Alright guys, I'm at my wit's end. I'm trying to setup Mac --> Windows XP Home printing over a wireless network for a friend. I've successfully set these things up before, and had my friend's system working until he got a new printer. Printer is hooked up to PC, MacBook is accessing it through WiFi. I've successfully added the printer through the Printer Setup Utility. Problem is I get an error when printing. I've attached a screenshot. All firewalls are off behind the router. I've also installed the proper drivers from HP. The MacBook used to be able to print to the old printer hooked up to this machine, so I don't think it's an authentication issue. Any ideas? Thanks.
