Thank you to everyone who has continued to contribute examples and feedback to this request. We recognize how valuable direct mobile printing would be for education, frontline, BYOD, and organization-issued tablet scenarios.
The Universal Print portal available today supports browser-based Secure Release for jobs that have already been submitted:
https://print.cloud.microsoft
We also understand that this is different from submitting a new print job directly from an iOS or Android application.
We are taking the requests in this thread into consideration as we continue evolving Universal Print. The detailed examples involving student iPads, Android tablets, shared devices, and printing outside Microsoft 365 web applications help us better understand and prioritize the mobile workflows customers need.
