I've been having a similar problem with Safari pdf files despite downloading the latest Adobe Reader XI.
I would constantly get messages - There was an error opening this document. The file is damaged and could not be repaired. And I would get a blank page when I tried to print the pdf if I tried printing from the Safari web page using File - Print from the top toolbar on my laptop.
If you're printing pdfs from Safari use the action icons on the grey lozenge that's positooned just below centre of the webpage.
Without downloading the pdf, print the pdf file direct from the Safari page using the Print icon on the above grey lozenge.
Saving the pdf by using the Save icon from this same grey lozenge on the Safari page you can open and print this pdf version from your desktop.
I've tested it with a couple of different pdf files and these methods work using the grey lozenge icons. But the same pdfs files don't work using File - Save As on the Menu Bar at the top of the screen.
