Package: libqt5printsupport5
Version: 5.12.5+dfsg-8
Severity: important


I have an up-to-date unstable system with CUPS and cups-filters                 
                                       
installed. cups-browsed is not installed.                                       
                                      
                                                                                
                                       
The Qt print dialog has two entries: ENVY4500 and LaserJet_300_desktop.         
                                       
The ENVY is an IPP printer on the network and the LaserJet is an                
                                       
advertised queue on a remote CUPS server. The enumeration is done via           
                                       
DNS-SD from the printer and the server and both devices are capable of          
                                       
two-sided printing. All ok up to there.                                         
                                       
                                                                                
                                       
Looking under Options, the duplex options are greyed out. Furthermore,          
                                       
"Advanced" under "Properties" is also greyed out. The latter means that         
                                       
a user cannot set values for Media Type, Color Model and Print Quality.         
                                       
Rather a disadvantage, I would have thought. Here is an output from
querying the printer:

If the printer or print queue is printed to, CUPS forms a temporary,            
                                       
local queue and a PPD is generated in /etc/cups/ppd from the queries            
                                       
made. This queue exists for a minute and during that time the duplex and        
                                       
Advanced options are available in the Qt dialog.                                
                                       
                                                                                
                                       
It seems to me that the dialog is not querying either printer or queue          
                                       
to get their attributes to display but, OTOH, is happy to deal with             
                                       
local queues, which is what cups-browsed supplies. It would be good to          
                                       
take full advantage of what CUPS offers and fix this unsatisfactory             
                                       
behaviour.                                                                      
                                       
                                                                                
                                       
Regards,

My desire to interact with this issue is very much diminished. Hence closing.
Thanks for your advice.
