Why is the client software preventing exit?

The application cannot be closed, because it is required to perform printing on this network.

This message is displayed when user interaction via the User Client tool is required before the job will print. E.g. confirm the job details or choose a shared account for the job. Only in these cases, are users prevented from closing the client. In all other cases, users are able to close the client.

From PaperCut MF v19.0, with a compatible MFD (see compatibility requirements here), running the User Client software is optional when you submit print jobs that require account selection, as you can complete that selection directly at the MFD. In this situation this error message can be safely ignored, or alternatively you can uninstall the User Client. For more information see Assigning accounts to print jobs at the MFD.

It annoys us when things in the system tray don’t have an exit option. We felt that users would think the same way about our software if we didn’t offer one. Rather, the option is there, and clicking it explains why it’s been disabled.

If you have a suggestion about how we could do this better, please add a comment below.

In managed Windows lab environments access to the task manager is generally disabled. If you can access it and you really want it gone, power to you.
