OS X 10.5.8 and 10.6.8
Office 2004 and 2008, Powerpoint and Word
No reported issues with 10.8 and Office 2011, no 10.7 installs.

Yes, these are old versions but these Macs are unlikely to get upgraded. Apart from the nuke-the-site-from-orbit option of a complete wipe, have tried all combinations of EFI removal tool, manual pref removal, driver reinstall, program pref removal and (on one) Office reinstallion.

The Macs have a bit of a think just after the print button is pressed and then Powerpoint/Word crashes. Problem appears intermittent but that may be down to user reporting - it's very likely that it is happening the majority of the time and they're just not telling me.

Anyone else seen the problem? EFI - don't suppose there's another version of the driver coming?
