I'm experiencing issues with trying to install new printers on XP, Windows 7 32 and 64 bit systems. When I go to the http://iprintserver/ipp page and click on a printer to install, the installation just hangs and eventually times out. I have a number of printers that currently have the same printer installed and are successfully printing through iPrint to the printer, but new printer installations keep failing with a timeout. Any suggestions? Thanks!
