Thank you. Support is first adding more RAM. The person I spoke with thought the TSPrint might be an additional cost but is checking.

Seems like it should not be an add on cost- the TSPrint website offers an unlimited license to servers for $299:

From their site:
Unlimited license

The unlimited license has no restrictions. You can use TSPrint on your terminal server no matter how many users are connected or how many printers each of them have.
