Hi all
I'm cross posting here as it seems this hasn't been discussed on Technet yet.
There seems to be a fundamental issue printing PDFs on 2012 R2 RDS.
Adobe Reader, Sumatra PDF, different printers & drivers all haven't fixed this issue.
At least one person has raised a ticket with Microsoft for this issue and they're apparently aware of it.

Can anyone help?
