Possible to rigger notification when printing?

Questions & Suggestions

Could Keyboard Maestro be a tool to trigger a notification when I send a document to a particular printer? I sometimes forget to pick up my finished jobs after working at my desk on tasks other than printing.

Or, is there another tool that would be better suited for this?

Printing the document may result in the printer utility specific to that printer being launched. If so, the Application trigger should be able to detect that happening.
