XP Presentation Server 3 with the following scenario:

Running a DOS based application on the server that can only print to LTP1:
Citrix clients are using networked printers and would like the DOS application to print to those.

How do I configure this?



Much appreciated!

The networked printer should be defined on each workstation as assigned to LPT1, and Citrx should be configured to allow LPT port mapping. When a user connects, their LPT1 is mapped and the legacy application happily prints to LPT1 which ends up on the network printer.

I'll give that a try. When you say Citrix configured to allow LPT port mapping. Is that configured in the terminal server settings?

I'm not in front of any of the Citrix components now, but I believe this has to be enabled both on the server (probably in the TS settings) and also on the client options.

ok, but if you're using the web version of the client, is there an option to do that?

If you need another way to get this working you can script mappings to the server's LPT ports.  For example, you could have a script do this

net use LPT2: \\ServerName\PrintShare

That would map a network printer to the server's LPT2 for your DOS application.

BLipman's suggestion works if the networked printer is accessible from the server, but if the networked printer is in a remote office, you need to get Citrix to support the port mapping.

Things are often version-dependent, but you should be able to set the LPT mapping option on the server and the web client should honor that.

Ok, ET0000, can you please confirm where I set this up on the server?

Ok, I think I have modified the server to map LPT. It was already enabled on Citrix RPC, but not on the Terminal Services.

Still no luck. I have no LTP1 mapped in the client on my Citrix session. Heeeeelp!

Sorry I didn't get back to you on the server config.

You can check the Citrix GPO policy (http://support.citrix.com/article/CTX104693&searchID=21693203), but I suspect you may be running into a limitation on the web client (I found doco saying the web client doesn't support COM port redirection, but couldn't find anything one way or the other about LPT port redirection).
