When using only redirected printers on a TSPlus server, sometimes ghost printers can appear in the printer folders each time a user logs off. This can result in an overall downgrade of the server performance.

To avoid this, let's set a group policy. Click start, execute, and type in gpedit.msc :
Open Computer configuration, and locate Administrative Templates/Printers/Prune printers that are not automatically republished.



Click Enabled, and select "Whenever printer is not found"



Doing so each time a user will log off, there will be an automatic deleting of unused redirected printers. My advice is also to manually delete all ghost printers as well and reboot the server especially if you experience a lack of performance.
