Hi, If you have Mac OSX 10.4 Installer Disks, the printer drivers are on there. They are in a folder of Additional stuff if memory serves. They are easily installed. HP has acknowledged to me that these are the latest and greatest and they do in fact work like a champ in OSX. Not sure if your printer has the Postscript level 3 RIP (mine is the 2500CP) if that makes any difference? Best of luck. So long for now, TOM
