We have a client that has Windows Server 2016 Citrix servers and when they print a PDF that opens in Adobe Acrobat DC it does not print. This is speradic and happens to different users and different printers, but always seems to be their default printer where it does not print. We updated the drivers on the printers. All other documents print fine to the default printers. Also if we change the PDF reader to Chromium Edge, it prints fine to the default printer. If we change it back to use PDF Reader as the default, then it prints to the default printer, but we either have to change the default printer or change the PDF Reader to Chromium Edge and then change it back to Acrobat reader and it starts working again. Has anyone had these issues before? They have Citrix Zenapp 7.5 on their servers. We checked all of the printer policies as well. We do not see any errors in the event logs pertaining to Adobe and or printing issues.
