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/
D [24/Oct/
D [24/Oct/
D [24/Oct/
D [24/Oct/
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/
D [24/Oct/
D [24/Oct/
D [24/Oct/
I think that the PPD is broken because it does not specify a resolution.
It would be nice if the PPD could be fixed.

FYI:
The attached PDF.ppd.gz belongs to

because it seems one cannot attach files to questions.

A year has passed - what do I need to do to get this PPD fix upstream?
The attached PDF looks very bad when printed in 300dpi and looks good when printed in 600dpi. Somehow this font makes the problem very visible, with latin fonts the difference in quality was less profound.
In 300dpi the lines of the letters look ragged and not crisp.
