Title:
  HP Officejet Pro X476dw MFP prints in 300dpi

Status in HP Linux Imaging and Printing:
  New
Status in “hplip” package in Ubuntu:
  New

Bug description:
  Running Ubuntu 14.04 running stock hplip 3.14.3

  Printer HP Officejet Pro X476dw MFP

  hp-check -t output is attached

  Problem:

  Initially I noticed that printing documents with Hebrew fonts results
  in low quality with fuzzy lines. 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.

  I was able to fix the problem by adding this resolution setting to the
  PPD:

  *DefaultResolution: 600x600dpi

  As a result the print job is converted at 600dpi instead of 300dpi
  which leads to the expected good result:

  D [24/Oct/2014:07:22:33 +0200] [Job 262] Printer make and model: HP HP Officejet Pro X576dw MFP
  D [24/Oct/2014:07:22:33 +0200] [Job 262] Running command line for pstops: pstops 262 schlomo hebrew-test.pdf 1 'Duplex=None finishings=3 media=iso_a4_210x297mm output-bin=face-down print-color-mode=color print-quality=4 sides=two-sided-long-edge job-uuid=urn:uuid:83e69459-c350-37e5-417d-9ca00f8c6bd9 job-originating-host-name=localhost time-at-creation=1414128153 time-at-processing=1414128153 PageSize=A4'

  I think that the PPD is broken because it does not specify a
  resolution.

  It would be nice if the PPD could be fixed.
