We are in the process of troubleshooting why the HP LaserJet Pro P1606dn once worked through Remote Desktop Services connections for remote connections to a Windows 7 machine but now does not. It works for remote to RDS sessions, but not for desktop RDP connections to this one machine.
The above link is good as of this writing. It has links to all versions that we may need to work with:
We already ran through the process of disabling the setting in Group Policy for the Remote Desktop Easy Print driver to be chosen first. Doing this has not changed anything so far. :(
From what we can tell, the print driver fails to install on this particular machine where on machines the driver seems to work as expected. So, we now know that the situation is isolated to this one machine.
Hopefully after we ground zero (wipe) the spool service setup including all drivers that we can get things to work as expected.
