jimav, thank you for reporting this and helping make Ubuntu better. We would
want to investigate any possible printing issue(s) with cups first before
claiming Adobe Reader has some discrepancy between OSs. Please execute the
following command, as it will automatically gather debugging information, in a
terminal:
apport-collect 997728
When reporting bugs in the future please use apport by using 'ubuntu-bug' and
the name of the package affected. You can learn more about this functionality
at https://wiki.ubuntu.com/ReportingBugs.
As well, could you please attach all relevant information from
https://wiki.ubuntu.com/DebuggingPrintingProblems ?

Title:
Ubuntu port of acroread degrades images (works on Win7)
Status in “cups” package in Ubuntu:
Incomplete
Bug description:
Certain images are substantially degraded when printing.
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]
Attached is a test file.
