Bug#977682: okular: Okular can't print Postscript files without cups-filter package installed

[Xavier Brochard <xavier@alternatif.org>]

Package: okular
Version: 4:20.12.0-1
Severity: normal

Dear Maintainer,

I'm using a network based cups printing without cups server on localhost (cups-client and cups-daemon are setup on my local computer, while cups-server is on the network).
While text based printing works well (web page from Firefox, LibreOffice document, text loaded in Okular), I can't print pdf files from Okular because of this lpr error :                       
Unsupported document-format "application/postscript"
Printing with qpdf works well.

Installing cups-filter package solve the issue.

Best regards
Xavier
