Terminal Server 4.0 – Print problem

Hi all,
I have a Terminal Server 4.0 System with a permissions, or some sort of problem that won’t let me print from within a Terminal Client to a particular Laset printer.

Even after re-installing in the drivers etc, ensuring full control access to users, the test print page brings up this error “The test page failed to print …. %1 is not a valid WINDOWS NT Application”

I have read an MS Article on “Application Security, but this is disabled at the moment.”

I can print to this printer locally from the server, as Admin, or user but not as Admin or any other user on Terminal Client.

Any help would greatly be appreciated.

Gavin
