This issue might be reopened by someone else who likes to adapt and enhance yast2-printer to what is needed by current CUPS and cups-filters. But there are no other issues (like user bug reports) in this area so that the current state could be even considered sufficient in practice. Accordingly it is questionable if further efforts should really be spend on yast2-printer. -- You are receiving this mail because: You are on the CC list for the bug.
