We have Adobe Reader DC - v21.007.2009x installed on all our Windows 2016 Citrix servers. Since the latest Reader release, we have experienced blank pages being sent to printers. The .pdf documents open and display correctly within the Adobe Reader window. However, after selecting File>Print and choosing the desired printer, the rendering of the print preview is a blank page and this is how it prints as well. This occurs regardless of the type of printer and user. Reverting to that last used version of Adobe Reader DC corrects the issue, but only temporarily, as the auto update feature automatically installs the latest version of the program.
