Since the last Windows 7 update, my LaserJet P1606dn, when set on duplex, prints the back page upside down. The operating system is Windows 7 64-bit. I have tried changing settings, I uninstalled the driver and had to reinstall using the CD (would not install using HP website). When I run the Troubleshooting, it says there are no problems.
Is there a patch that will fix this? Am I missing something? This is really frustrating. Thank you for any help.
