Hello,
We have an HP LaserJet 4250n with an envelope feeder installed on it. Most of our users are currently using TP v. 7.6.56 and printing to the envelope feeder works fine over Windows Remote Desktop / Terminal Services. However, when we upgrade to v. 8.x, printing to the envelope feeder no longer functions--print jobs simply print to the regular printer tray. Further more, uninstalling v. 8 and reinstalling v. 7.6 results in the envelope feeder still no longer functioning. The uinstall of v.8 consists of performing the uninstall from Add/Remove programs on Windows XP, and removing the ThinPrint registry keys from both HKLU and HKLM \Software\.
I have spent hours and hours trying just about every possible printer setting, preference setting, and driver combination, none successful.
I HAVE found success by performing a Windows System Restore on workstations I have attempted upgrading to v. 8. Unfortunately we have a few workstations that have already been upgraded and then downgraded many months back so performing a System Restore can't really be done on these workstations.
Printing to the envelope feeder works perfectly in any windows application--Word, Excel, etc.
It seems logical to me that there are some other registry keys or application components that the v.8 uninstaller is not deleting.
Would appreciate some help with this as our users use this envelope feeding for mass mailings and its simply not feasible for them to use the manual feed of the printer.
Thanks!
