DOSBOX, Megabuild v6

So I have a DOS application that prints to LPT1

I need to send the print job to a network based printer. I can manage this no problem with a Windows 7 x64 based host machine by using:

NET USE LPT1: \\computer\sharename

The problem I have is that the host machine isn't Windows, but a Mac running OS X Mountain Lion

Has anyone managed it?
