The PowerShell script automates resetting the Print Spooler by deleting all print drivers and print queues only for Windows 7 and Windows 2008 R2 Remote Desktop Servers.

This performs the same cleanup and is the script behind the FixIt for KB 2793718 You experience Print Spooler error messages after installing or upgrading a Third-Party print driver http://support.microsoft.com/kb/2793718/en-US.   

Supports only Windows 7 and Windows Server 2008 R2 Terminal Servers/Remote Desktop Server Host machines. This tool will run on Servers with Print Role installed but will not make any changes. Please find more information about the KB and the FixIT from http://blogs.technet.com/b/askperf/archive/2013/05/22/3482664.aspx?PageIndex=2

The script is not signed so the PowerShell Execution Policy must be set prior to running:

1. Start PowerShell in Admin mode
2. Type following command Set-ExecutionPolicy Unrestricted

Following command resets print environment to out of box: print-reset.ps1 -full

Following command corrects common printing issues: print-reset.ps1 -light

Explanation of Light Mode and Full Mode

-light: Light mode - Corrects common printing issues.

1. Stop spooler service and dependents.
2. Do not backup spooler service configuration: hklm\system\currentcontrolset\services - warn user -printbrm/PMC
3. Do not Backup print configuration: hklm\system\currentcontrolset\control\print
4. Do not backup files in %windir%\system32\spool\printers\ directory - warn user - back up manually
5. Import default print monitors (USB, Local Port, TCP/IP, WSD, and Microsoft Shared Fax registry configuration)
6. Import spooler service default configuration
7. Import print processor configuration for correct machine architecture: hklm\system\currentcontrolset\control\print\environments(machine architecture)\winprint
8. Detect if spoolsv.exe, spoolss.dll, localspl.dll, or win32spl.dll are not present in %windir%\system32, write error to log.
9. Copy NTPrint.inf from %windir%\driverstore if not present in %windir%\inf. If (also) not present in driverstore, write error to log.
10. Test the path for hklm\system\currentcontrolset\control\print\printers.DefaultSpoolDirectory. If it is not a valid path, write error to log. Correct this condition by setting it to the default path.
11. Delete all files from the spooler directory
12. Start the spooler service and dependents

-full: Full mode. Resets spooler service and print key to defaults.
