On the Uniprint side, the Mobileprint App you speak of is only for printing from iOS Apple phones, they are still working on one for Android. You can send a job from any device that supports email. Mobileprint works via email, or by uploading from the "desktop" via the Pharos Print Center. I'll assume that when compatible, Mobileprint would interface the same way with Blueprint.
That is correct.
Coming for Blueprint 5.2 will be the Mobile Print function as it is currently works with Uniprint 9.0 (with service packs and hot fixes applied).
Mobile Print allows users to email documents into the Secure Release Here system. With Pharos Print Center (PPC) you can upload files from a computer to be released as well as manage your jobs. The iOS application allows a user to submit jobs into the SRH system and manage the jobs like deleting them and switch from mono to color.
If you can access the PPC web page on your mobile device (iOS or Android), you can then login like you do to the PPC web site and print your job from there. Some customers choose to disable the ability to Print A Job from the PPC web site for varying reasons.
