Last night I tried to print a PDF that contains color, and it came out in grey scale. I discovered that this happens when I open the file with Adobe Acrobat Pro XI (the default association for filetype PDF).
When I use the version of Adobe Reader that I originally installed on my computer (version 9), I get color.
I've searched Acroat's s print options for a setting that might cause this, but I've found nothing. All I found was two options on the Print Properties dialog's Imaging tab named "Print text as black" and "Print graphics as black." Both of these are NOT checked.
What's making Acrobat behave this way, and how can I stop it?
