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
