Bug 446417

SUMMARY
 I have a Brother printer, a MFC-L2700DW to be specific.
when GUI to add the printer, it gets discovered in the wizard, but when the wizard is finished, the printer does not get added. and does not show in the GUI.  

Trying to print with okular, gives me the option to print with the printer even before trying to add the printer, tho the printer name does not match exactly (some underscores replacing spaces and other differences like that), so i assume it is not the one i tried to add, specially since trying to use that printer does nothing. the same happens in the system print menu.

I tried this in bot my 
laptop: running Manjaro
desktop: running EndevourOS

On my laptop, I had the same problem, but  when I connected it to the printer USB, i got it automatically added and even working trough the network, no configuration required.

Cant physically connect the desktop via USB...




STEPS TO REPRODUCE
1. open system settings
2. go to printers (should be empty)
3. click on add a printer
4. Select under discovered network printer 'Brother MFC-L2700DW series'
5. Select under recommended drivers 'Brother MFC-L2700DW series, driverless, cups-filters 1.28.10 (en)'
6. next and finish.

OBSERVED RESULT

the printer does not get added nor shown in the GUI, nor is accessible in any printing panel (only the ghost printer mentioned before)  


EXPECTED RESULT

the printer  gets added with the name specified on the wizard and is accessible trough okular, firefox, and system print menu
