I believe I encountered a bug with the latest VDA 7.12. In my environment we use the Universal Print Driver (UPD) with client mapped printers. If we print from any other applications besides Internet Explorer (IE) 11 and I select a different tray then tray 1 then the prints come out the correct tray.
However if I do the same from IE 11 then prints always come out of tray 1 no matter what tray I select. If I change the VDA back to version 7.9 then we do not have this issue.
I'm posting to see if there any other engineers out there that witness the same. If you do then please respond to this post.
I already have a case open with Citrix for this (Citrix case 72333339).
