This has been an annoying problem for a while now. There are numerous threads on this issue and no fix (that I can find). The work around is to print single sheets. For a massive print job like Xmas cards - this is laborious. I am on Windows 10. The Print option use to work. My HP printer works with other applications. The press space bar while clicking the print option does not work. Ctrl P does not work. I do not have access to my print dialog box. Deleting preference files and starting up again does not work. I have read that some got help from Adobe by allowing them to take over their computer and make changes to the registry file. Some say the problem is due to a Windows Upgrade. Please Help.
