generic text driver on client not sending printer commands

[kcs]

I am deploying a 2008 ts server, and the clients have a generic text
driver which includes printer commands for 'end print job'. the
problem is that these commands are not being sent to the ts session,
so therefore these commands are not included in the printer output.
Because of the (new) nature of server 2008, I cannot update the
redirected printer on the ts end to include the printer commands.

is there a way to update the printer properties, printer commands, end
print job on the server end, or better yet, is there a way that when
connecting to the ts server, the client's printer commands are
automatically included?

thanks in advance.
