I have over 50 users with Adobe Reader 9.3.3 installed. Every morning someone calls and says Adobe Reader reported that there are no printers installed on their system. When I check their PC I find that the default printer setting has been removed and there is no default printer set. Once reset they have no problems with the printers or their other applications. This only happens when trying to print a PDF.
Why is Adobe Reader removing the default printer setting?
Adobe Reader is not capable of removing a Windows printer driver.
The driver has NOT been removed. Just the default setting.
In very PLAIN English the default printer check mark is GONE.
