Problem
Print jobs will print out blank.
Cause
The windows print spooler folder where the job is rendering lacks the correct permissions for users.
Applies to product
ThinPrint Engine (any version)
ThinPrint RDP Engine (any version)
Solution
Check the permissions for C:\Windows\System32\Spool\printers and add checkmark to the effective permissions.
Then go to services.msc and restart the print spooler service.
