[FFe] Add qtubuntu-print (and ubuntu-printing-app) to default unity8 experience

[Andrew Hayzen]

We want to add printing support into the default unity8 experience.

Adding qtubuntu-print as a recommends (which itself recommends ubuntu-printing-app) adds:
- a printing plugin to Qt, so that when something is printed it is sent via content-hub to a destination app that is opened in a trust session.
- a destination app, which acts as the print dialog in the trust session for choosing print options
- a printer queue for hold/release/cancelling jobs
- a notification when something is printed or there is an error on a printer

Note without these packages installed the queue dialog button already in ubuntu-system-settings will not function.

The MIRs for the extra packages are:
qtubuntu-print: bug 1673809
ubuntu-printing-app: bug 1673808

Having these packages does not adversely affect Unity7 as the qt print plugin and notifications only occur on unity8. Also the desktop files are not show in Unity7 (as of silo 2642).

This seems reasonable. The dependent packages have MIRs and those are already approved. Please reference this bug in the upload.

This bug was fixed in the package unity8-desktop-session - 1.0.13+17.04.20170328.1-0ubuntu1

unity8-desktop-session (1.0.13+17.04.20170328.1-0ubuntu1) zesty; urgency=medium

  * Add qtubuntu-print (which has a recommends of ubuntu-printing-app)
    as recommends of unity8-desktop-session so we can have printing (LP:
    #1676436)
