PrintUI.dll Error Handling

It seems like the PrintUI.dll has a different error handling system than the typical command. If I try to run a conditional command like:

(rundll32 printui.dll,PrintUIEntry /y /n "foo") & (echo Success) | (echo Fail)

This command will evaluate as false but the error alert isn't suppressed. How do I suppress these alerts?

Error:

Solution

  • I found the answer. You must include Modification Parameter /q.

    (rundll32 printui.dll,PrintUIEntry /y /n /q "foo") & (echo Success) | (echo Fail)
