Also, and I must say that my Advanced Print Manager 4.0 will add a GUI around configuring the UPD key I just sent. :-) Makes it really easy... www.dabcc.com/apm.

Brown Sent: Friday, July 08, 2005 1:57 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: PCL5C UDP John, I don't recommend deleting the driver. It won't cause you any issues but it is not needed. Check this out: The Citrix Universal Print Driver has the following registry entries: The key HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\UniversalPrintDrivers\ * Value:DriverList * Data of Type REG_SZ: PCL4;PS;PCL5c. If you remove PCL5c, the printer is mapped as PCL4 and if you remove PCL4, the printer is mapped as PCL5c. If you leave only PS, no printer is mapped. The "PS" universal driver is intended for use with UNIX Clients, where Postscript is the default printer control language. So for you I would edit the above key to read PCL4;PS Make sense?

The new UDP does not work for us. I am wondering how I could force these servers to use the old Citrix PCL4 Universal Print Driver. Looks like I might be able to just delete the HP 4500 PCL driver from each server. Seems like there should be more to it then that. What says you?
