If I pull document properties with Adobe Reader 9 (of your attached copy), it says it can be viewed/printed with v7.0 or higher. Printing isn't restricted, editing is. I've seen the shrink to fit margin issue cause problems quite frequently. I really don't see a point in trying to "crack" an unlocked file.
How does the Reader Print to File option behave ... And what if any error messages are there?? Does it get stuck in the spooler...or does it just not do anything, and vanish?
