ghostscript_9.50~dfsg-2 packages have been uploaded, with this bug probably still unfixed and unknown to upstream. I was not able to actually test my printer with 9.50 yet, but changes in upstream git don't seem to address this bug, and it's not in upstream butracker.
Question to the package maintainer: Are you going to forward this bug to upstream or is more action needed from my side? Thanks, Johannes
