We've noticed an issue with our new Windows 7/Office 2010 installations when printing a landscape page to a network printer (all using the HP Univeral PCL5 Driver for 32/64 bit compatibility) - it either prints in portrait, or the print job is created (i.e appears in the queue) and then disappears without printing anything.

The older Xp clients are fine, so I'm not sure whether its office, Windows7 or the driver itself - although HP say thats the driver to user for pretty much all of their laserjets these days! Anyone else had a similar problem?
