unable to print pdf with okular( lpr usage error)

[P]

open a PDF file with okular
file => print => choose printer

nothing happens on the printer
no file appears in printer queue

on /var/log/syslog I can see the following errors :

Can you please enable backports and try the newer version 23.08.3 and let me know if it still an issue?
Thanks

I add ppa/backport
now I use the correct version 23.08.3 but with same result :
no printing and the following error in syslog :

usage: lpr [-cdfghlmnpqrstv] [-#num] [-1234 font] [-C class] [-i [numcols]]
        [-J job] [-Pprinter] [-T title] [-U user] [-wnum] [name ...]

is there a mean to get the lpr command generated somewhere ?

[Scarlett Gately Moore (scarlettmoore)]

Possibly this: https://bugs.kde.org/show_bug.cgi?id=440131
Can you please try and install cups-bsd

[P (p92)]

nice catch - that was it : lpr package installed instead of cups-bsd

it now works ok.

shouldn't okular introduce a dependency on cups-bsd ?

[Scarlett Gately Moore (scarlettmoore)]

Yes, it seems like it should. It is too late fr mantic, but will fix it for noble. Thanks for your report!

[Scarlett Gately Moore (scarlettmoore)]

Alright, it seems it is already fixed for noble, hence why I didn't get error.
