When setting up Email to Print with a Gmail mailbox there’s one common issue that’s reported to PaperCut Support quite often.

You’ve entered the IMAP settings correctly in the Options → Mobile BYOD → Email to Print but it’s not starting.

You may also see an Error while fetching mail log entry in your Application Log, under Logs → Application Log. As Below:

If that’s the case, then please check the Gmail inbox you’re attempting to connect to PaperCut for Email to Print. You could have an email about a blocked sign-in attempt from a less secure app as below:

The reason for this is because by default Google will block sign-in attempts from the PaperCut Server.

Up until May 2022 the solution for this was to allow “Less Secure Apps” to access the mailbox account by logging into the mailbox’s Google account and going to the following page: https://myaccount.google.com/lesssecureapps . However since then Google has formally ended support for Less Secure apps.

The new solution is in our article Setting Up Google OAuth2 for your Gmail account for Email to Print.
