Hi! I'm brand new to OS X, and I'm trying to set up my printer with my new iMac. I am running 10.4 I downloaded and installed the necessary software from HP. After installation, it entered a setup assistant. The setup assistant had a couple of steps: 1. Launch Printer Setup Utility by clicking the button below (done) 2. Click Add Printer (done) This takes me to the Printer Browser. In this screen, I have "Default Browser" selected, and in the main table, I can see my printer (HP Photosmart 7550) with a USB connection. If I click this printer, the name and location boxes are automatically filled in, but "Print Using" is left blank. If I click the drop down menu, I can scroll down and find HP. Unfortunately, my printer (or any photosmart printer) is not included in the list. 3. Click on "More Printers...". Select "hp photosmart" in the drop-down list. This brings me to a small popup with several options. The first is a drop down menu which has defaulted to "Windows Printing." The other options include AppleTalk, Bluetooth and others. Beneath this is a second drop down menu, which has defaulted to the "workgroup" option. There is an empty box, a grayed out Printer Model drop down, and that is all. I cannot proceed past this point, and am altogether stumped. I have tried numerous things, including installing the newest version of Gutenprint and following the instructions therein. This leads me to the exact same dead end. Help please?
