From time to time sys admins will reach out to us about a strange quirk of print scripting, where the same pop-up will appear multiple times causing confusion for the end user.
This can occur if the print script requires user action for the job to be printed. The printjobhook runs multiple times during the hold release process. When prompting a dialogue from the printjobhook to users (e.g. prompOK) and the text of the pop-up may change after one iteration of the printjobhook, such as using an inconsistent variable or new timestamp, a pop-up can repeat. The default method of identifying an already invoked pop-up is by it’s contents. If these change then the script will start up another pop-up. This is by design as some scripts require multiple pop-ups with different questions or information.
