We have a new fresh SLESSP3/OES2SP3 install running iPrint. We have not been successful at creating a printer that uses HP's Universal Print driver (v5.2). The creation of the printer goes fine and every thing looks good, but when you visit the iPrint web page and click to install the printer you only get the "Loading Printer" pop up. This will just run and run until eventually the computer locks up. Rebooting lets you check the printer and it shows as installed and says so if you try to reinstall via the web page, but regardless no print jobs are processed. Any suggestions?
