I am guessing you get this because there is no default printer. Notice in the background it says "No Printer Installed"

That's because when the printers are being parsed for selection its failing. Originally, there is a default printer. We had to edit the swpset program to allow for 512 printers to be loaded. That fixed the problem temporarily. We need to figure out why so many printers are being loaded. I suspect this is a TS issue.

I would turn off printer redirection on TS then remove the printers from the TS so they no longer show in the TS printer list. Not sure if you can do it with a group policy but I would think you could instead of changing each rdp shortcut.
