iPrint Email Printing: 

iPrint has the feature (Email Printing) to submit print jobs using an email account. The user can send an email to an email account configured for an iPrint printer. This feature requires the email account to authenticate.

Problem:

Google enhanced their authentication the end of May 2022. With the May 2022 change, email printing through GMAIL stops working.

Resolution:

To enable Google Email Account for iPrint's Email printing, Google's "App passwords" needs to be used for authentication.

Generate Google "App passwords": (Ref: https://support.google.com/accounts/answer/185833?hl=en )

• Log into Gmail with the iPrint Global email account
  • These same steps will need to be performed with the individual printer email addresses
• Click the Gmail Account icon in the upper right.
  • Click the "Manage your Google account" button.
    • Click "Security" on the left menu.
    • Enable/Configure 2-Step Authentication
      • This will introduce the ability to configure "App passwords"
    • Configure "App passwords"
      • Choose "Mail" in the "Select app" drop down
      • Choose "Custom" in the "Select device" drop down
        • Create a name, such as iPrintAppliance
      • Click the "GENERATE" button.
      • Record the generated password
        • this password will be needed later.
