RAMP CITRIX Macintosh Null Printer

I'm using Citrix from a Macintosh client to connect to RAMP.

Has anyone successfully setup a NULL Printer in this configuration so that one can test ticket sales all the way through Ticket Printing.

I don't really need to connect to a Boca to Print Tickets.  I just need to be able to complete an order on MOS that requires that tickets be printed before closing an order.

Any thoughts or documentation let me know.

Thanks.
