I was one of those that could not print from a Doc Tray. As suggested, I removed then reinstalled Adobe Reader. Printing from the Doc Tray was reestablished (for a while). I then installed DW on a laptop and could not print from a Doc Tray. I uninstalled Adobe Reader then reinstalled it but still could not print. I then uninstalled Reader, rebooted the laptop, then reinstalled Reader. Still could not print. I even used Adobe’s cleaner and still have the problem. Went back to my workstation and test printing again and could not print from a Doc Tray once again. Uninstalled and reinstalled Reader but still can’t print. The only way that I could print was to go into IE add-ons and disable The Adobe Reader add-on. The only thing is that when the document comes up, it is blacked out but the print screen comes up and I am able to print the document. Once the document is printed, and the print box closes the document appears as normal. I have discovered that if Adobe reader is enabled and I try to print from the Doc Tray, I get the blank page as before, but if I then refresh the screen, the page loads normally.
Checked with another staff having the same problem, and after removing and reinstalling Adobe Reader, no change, but the refresh corrects the problem.
