@Till

some more tests:
- the pc was already running, but the printer's usb cord was unplugged. So i plug it again, then set the printer 'on' via its on/off switch button. Start a printing job: done as expected.

- then let the printer plugged (usb cord) but the printer powerded down (on/off printer button)
- wait about 15 mn without printing
- then powered on the printer and try to print something again to test the previous 'usb port not awaken' issue reported here. The printing job have been done as expected.

To conclude about that report: the apparmor 'enforce' status seems the
only one to be blamed, as the 'complain' status set let the usb port
active.  The 'hplip' report (lp:241781) seems also refer to the same
apparmor config issue. Note that i've declared a false positive about
the missing job inside the queue; sorry about that.
