Wireless network printing with HP printer Lipnus to XP

Hello all. To start off, I'm not a complete dope and I've been able to get other printers work on the network without a problem. I recently bought a low end colour laser printer, the HP CP1215. To get the printer to work in Linpus, I had to download the updated CUPS for HP printers. I've done that and I am able to print directly from my AA1 to the printer via USB, but when I plug the printer back into my XP box, I cannot get the AA1 to print to it via network. I cannot find it on the network with the new HP install Wizard that came with the CUPS update, but it does show up on the network when I go to add a new printer normally in the settings and select the proper driver, but it will not print over the network even if I choose the exact same driver! Any thoughts on how I might be able to get this to work???
