Bug Description
Certain images are substantially degraded when printing via acroread (but not degraded when using lpr).
The problem only occurs with Acrobat Reader on Ubuntu,
not xpdf or Acrobat Reader on Windows 7 (using the same printer and input PDF).
So there is something wrong with Acrobat Reader on Ubuntu specifically (or maybe any Linux).
The printed image appears darkened or the available grey-scale resolution is lesssened. The test image (attached) is blueish and the printing was on a monochrome laser printer (hp3030), so the problem might be related to mapping colors to greyscale.
The PDF was created by exporting from Libre Office Writer with PDF/A and "Lossless" image compression.
Here are the exact versions of Acrobat Reader I tested:
Windows 7 (32-bit): Acrobat Reader 9.5.0 [works]
Ubuntu (both 64-bit & 32-bit): Acrobat Reader "9.5.1 03/07/2012" [image degraded when printed]
POSSIBLE WORKAROUNDS:
To just print the whole file: lpr AcrobatTestImag
To print only odd (or other selected) pages, for duplexing:
pdfjam -o file_odd.pdf file.pdf '1,3,5,7,9,11,...' && lpr file_odd.pdf
(There is no 'give me all odd pages' option to pdfjam so every page must be enumerated)
