Comment 0 for bug 1815307

System: Ubuntu 18.04
system-config-printer version: 1.5.11-1ubuntu
printer: Canon iP7250

I expect to be able to see the printer in the panel just as 'lpstat -l -e' or 'driverless' can see them, without the need to especially add a new printer.

And if I do need to add it (don't see why that should be the case, but still), I expect that choosing the printer's name under network would result in adding the printer.

What happened instead:

Canon iP7250 isn't shown in the Printers panel, clicking on add and expanding the network options - it is shown, but when trying to add it (either driverless IPP, LPD via DNS-SD or IPP via DNS-SD) it gives an error about CUPS internal error.

`$ lpstat -l -e` gives
`Canon_iP7200_series network none ipp://Canon%20iP7200%20series._ipp._tcp.local/`

So the system does see it, and `lp -d Canon_iP7200_series /etc/nsswitch.conf` does print (and for a minute the printer is shown in the Printers panel - but then disappears).

I can add it by *not* clicking on the printer's name under Network, but rather, click on ipp printer and manually choose Canon -> iP7200 -> CUPS+Gutenberg driver (and not the recommended driverless option - which, if I choose results in that same cryptic error I get when trying to add the printer by clicking on it, as described above).
