RDP Printing stopped working

Environment is Server 2012 and win7 pro clients (across WAN)

Issue is RDP was setup on the server with licensing server etc the whole 9 yards.  Printing redirected fine.  The time ran out and after realizing they only needed 2 connections and not even at the same time, they decided to not purchase the license and just use the 2 built in ones.  Switching to this made the users come up with an error msg about having rights etc, which an answer was found by modifying group policy on the server security adding Remote Desktop Users group in addition to Administrators.   Worked great, now the 2 users can RDP once again.  

But now they can't print anymore.  The redirected printer doesn't show up on the server either.  Would making the above switch affect RDP printing like it did?

Windows only allows two RDP connections *for admin purposes.* There are not two "free" connections for end users. As such, yes, you will hit technical limitations and oddities. You  also run a high risk of being caught and fined for running an illegal setup. *Every* end user connection (even if there is only one or two) requires RDS set up and CALs purchased.

Sounds good.  I'll have them purchase a 5 pack then.  I thought that RDP printing worked for admin related sessions also, was this changed in Server 2012?  I mean after they purchase the license is printing going to start working or do you think there is some issue going on.

It wasn't changed in 2012, but certain defaults have long been different between admin connections and an RDS server. Installing the role makes several changes such as the remote desktop users group that you had to force via group policy. The changes to the printing model, easy-print drivers, and the defaults in availability happened in 2008.
