Today I received my HP printer and started setting it up. Everything worked fine installing it on my windows 7 PC. Now I plugged the printer to my mac via USB. the mac recognized the printer started downloading the software and all. Now that that's done I put in the disk that came with the printer and I get the error message saying that my OS (Lion) is not supported. HP's website tells to check for software update and download the new update but Apple updates can't seem to find it. HELP!!!!
