Why does the "Test print page did not print correctly" error occur via RDP on Windows Server 2008 R2?

Question

System administration

On one of the machines, a printer is shared, a computer on win 7. It has access to it from a neighboring computer. On a neighboring computer there is access to RDP from 1C. The connection itself provides access to local printers. Everything worked until today. Prints everything from the PC itself.

Answer 1

In RDP session: Start -> End session, reconnect and check. Often such a simple action helps.
If it does not help, then restart the "Print Manager" service on the server, to be sure, after that, also end the session and reconnect.
