Good. Both these HPLIP queues use the same filters. The margin issue is<br>
minor.<br>

cup.service is an invalid service name. I actually gave cups-browsed as<br>
the service to stop. This was only to demonstate to you that the queue<br>
which keeps coming back is managed by cups-browsed.<br>

Good. This is a driverless queue auto-created by cups-browsed. It has<br>
nothing to do with HPLIP.<br>

There are three devices shown by 'lpstat -t'.<br>

The interface used shouldn't matter.<br>

You have indeed, and it shows you have a working printing system. You<br>
can, if you wish, do more testing with a more varied selection of files<br>
printed with different applcations.<br>
<br>
Here is what I would do on your system for printing:<br>
<br>
1. Decide whether to use one or other of the USB or wireless connections.<br>
<br>
2. If USB is chosen, delete the two HPLIP queues. You could also purge<br>
HPLIP from the system as it is no longer used.<br>
<br>
3. If wireless is chosen, uncomment "CreateIPPPrinterQueues All" in<br>
/etc/cups/cups-browsed.conf" and restart cups-browsed. Delete the two<br>
HPLIP queues. You could also purge HPLIP as it is no longer used.<br>
<br>
Keep things simple; you do not need USB and wireless at the same time.<br>
And, by using driverless printing, all HPLIP bugs can be avoided and<br>
nobody need bother about installing non-free plugins for printing ever<br>
again.<br>
