We have an issue: we migrated iPrint from Netware to OES11. If we try to print from IE8(on top of XP SP3) with File->Print... the browser session freeze(Not responding...). Somethimes, after a long period of time, the print windows appear and from time to time the document is even printed. In most cases it does not.
If we open pdf file from example from inside IE it works. Everything else seems to work(we can print from any application). On Windows 7 it works(different version of IE).
If we uninstall the printer from the OES11 iPrint and install one from the Netware iPrint in works!

Any ideea ?
