Ok,.... sorry to flip flop.... The problem that I thought I had fixed, actually still exists.
While i am finally able to print to PDF from Chrome, I still can't print under applications such as Word, Excel, my email client, etc etc.
I spent a lot of time on the phone with Adobe tech support today. Tried many 'solutions' including using a special tool for a clean un-install of Acrobat, and then re-installed the application under the Admin account. Nothing worked.
Finally, after hours on tech support line, it was determined that there is some policy setting under my operating system (Win7 Pro) user profile that is preventing Acrobat from printing. Adobe tech support wont touch it. They claimn it's Microsoft's fault and they wont get involved.
This sucks.
