We have a variety of clients using our print server and connecting via Citrix to access published applications.
Our print server is Windows 2008 R2, our Citrix servers are Windows 2008 R2, our printers are mapped to the PCs via GPO and the PCs in question are all Windows 7 64-Bit SP1.
We are using the HP Universal Print Driver on our Print server v5.4 (yes I know there are newer versions available but this one has passed all of our internal testing) - this is used for all of our printers and works quite well on the Client side.
However, staff are reporting that when they connect to the published application and go to print through windows from the citrix server that they are being prompted to "Add a Printer". If we have the staff member log out of their published app and log back in generally speaking they will hit another server and they'll be able to print just fine.
This problem occurs for all printers on a given PC when it happens, this includes printers mapped via GPO on the print server; locally installed printers that are connected via IP (legacy devices that we have not yet mapped to our print server); locally installed printers that are physically connected to the PC via USB cable - NONE of them map when the problem occurs. We can have two staff connected to the same server, using the same mapped printer and one will have the issue and the other will not.
Looking through the event log, I have found the following information in the PrintService events, there appears to be two events one after the other related to the attempt to map the printer:
Failed to upgrade printer settings for printer \\CSR|print1\{1005AFC7-7255-4E66-B6A3-657C7458ED3D},604,LocalOnly driver C:\Windows\system32\spool\DRIVERS\x64\3\hpmdp118.dll. Error: 0. The device settings for the printer are set to those configured by the
manufacturer.

I am presently at a loss on how to proceed.
