Please enable universal printing available on mobile clients so business users are able to print directly from phone or tablet.
As a mid-large K-12 district with 1:1 iPads for all students, we're still - for the sole purpose of letting students print - maintaining computers that take up space in the media center.
Those computers also have to be connected to a print server, since Universal Print can't handle tying a roomful of shared computers to a specific printer (no way to deploy a printer device-wide and make it the default for everyone when logged onto that computer, like we can with Group Policy Preferences and Loopback mode).
Those legacy desktops are only used for printing, and can go away (and free up valuable school library space) as soon as we can let students print from their individually issued iPads.
