When a remote printer is defined on a UIA+Profile Writable Volume and the printer is attached to its print server through a USB interface, the printer definition on the Writable Volume might get deleted on the next non-persistent logon. 
On the system volume, add the following two scripts to %SVAgent%\Config\Custom\uia_plus_profile:
OnPreLoadApp.bat: sc config spooler start= disabled net stop spooler OnPostEnableApp.bat: sc config spooler start= auto net start spooler
If you already have the same script names on the Writable Volume, add the spooler commands to the scripts.
When a script is present on a Writable Volume and in the system volume at %SVAgent%\Config\Custom\uia_plus_profile, App Volumes agent runs the script present on the Writable Volume and ignores the script on the system volume. To ensure that the App Volumes agent runs both scripts, you can add the following to the script on the Writable Volume:
if exist "%SVAgent%\Config\Custom\uia_plus_profile\%~nx0"
