I do not exactly understand what you described as
your "network setup" but regardless of it, to send
whatever data unchanged to a printer, set up a so
called "raw" queue, see the CUPS documentation or
http://en.opensuse.org/SDB:CUPS_in_a_Nutshell

You can set up two queues for the same printer:
A normal queue with filtering for usual applications
and a "raw" queue only for your DOS application.

If you can change the lpr command which is called by dosemu,
you don't need a "raw" queue, instead only add the "-o raw"
option to the lpr command which will enforce "raw" printing.


Kind Regards
