After some debugging I was able to trace this down to the fact that by default CUPS converts the print job to a 300dpi PS before giving it to the hp driver: D [24/Oct/2014:07:22:01 +0200] [Job 261] Printer make and model: HP HP Officejet Pro X576dw MFP D [24/Oct/2014:07:22:01 +0200] [Job 261] Running command line for pstops: pstops 261 schlomo hebrew-test.pdf 1 'finishings=3 media=iso_a4_210x297mm output-bin=face-down print-color-mode=color print-quality=4 sides=one-sided job-uuid=urn:uuid:c1da9224-d10b-3c2f-6a99-487121b8864c job-originating-host-name=localhost time-at-creation=1414128121 time-at-processing=1414128121 Duplex=None PageSize=A4' D [24/Oct/2014:07:22:01 +0200] [Job 261] No resolution information found in the PPD file.

It would be nice if the PPD could be fixed.
