I just stumbled on this problem myself, so went to Novell patches and
found they have a new one for iprint, a beta, addressing "NetWare iPrint
server updates, including iPrint server NLMs and an updated iPrint
plug-in. Numerous fixes are included with these updates and an
enhancement to increase compatibility with the HP Universal Print
Drivers used with Printer Driver Profiles. Windows 7 support and Auto
Driver/Profile update are also available with this release."

It's from April 20th and called iprntnw65sp8c.
