Printer Cleanup.exe 2642149382

Use caution when using PrinterCleanup!

Example 1: Using PrinterCleanup to control printer entries used by some applications​

Problem: Some applications read registry entries to display the available printers.

Background: There are 2 keys, HKCU\Software\Microsoft\Windows NT\CurrentVersion\Devices and

HKCU\Software\Microsoft\Windows NT\CurrentVersion\PrinterPorts, that contain the names of

printers. These keys are maintained by Microsoft, values are added when a printer is added and

removed when the printer is deleted. Windows does a poor job of maintaining these keys; usually

adding but not removing the values when a printer is deleted.

It's usually not a problem but some poorly designed applications read the values in these keys and use

them as a valid printer list. A properly designed application uses the standard print dialog to display

printer choices for the user (Notepad and Word for example).

 Solution: PrinterCleanup.exe can help maintain these keys by removing invalid entries. Several customers are using this method and they love it.

Implementation: Setup a Run value to do the work when the User logs in:

Implementation: Setup a Run value to do the woTo show the status of orphaned printers without doing anything, use:

"C:\Program Files\Tricerat\ScrewDrivers\Endpoint\PrinterCleanup.exe" -removeOrphaned -validate

This will produce a log in the C:\ProgramData\Tricerat\Logs folder that describes what actions it may take. This is safe to run anytime. If this step finds any issues, you can remove the -validate argument to perform the removal:

"C:\Program Files\Tricerat\ScrewDrivers\Endpoint\PrinterCleanup.exe" -removeOrphaned

Please gather the generated logs and submit to Support for review.

Note: If executing from a PowerShell Admin prompt, use this syntax:

& "C:\Program Files\Tricerat\ScrewDrivers\Endpoint\PrinterCleanup.exe" -removeOrphaned
