Chris,
So after reviewing the other thread it confirms my and your suspision, it is obiously a driver problem for Windows 7 PCs. BTW both of my Windows PCs have the problem, one is 32 bit other is 64 bit.
How do we ask HP to fix this in a driver update. This printer is one bought/used by a large audience, been out for a while now and thus should have enough of an install base to warrant HP fixing the driver by now.
I checked, there is no setting in the Printer menus on the machine itself to disable Duplex (and I don't want to lose the Duplex function all together).
Advice appreciated on how to ask HP formally to fix this in the Windows 7 Driver asap.
Regards,
