It is my belief you are just adding a driver to your printer server and will not break anything with your legacy connections. What is the model of printer you are using, that will play a big role.

Subject: [MSUNAG] 64 bit Print drivers on 32 bit Print Servers?

Hi all,
Right now, I'm running a 32 bit Server 2003 machine which is also my
print server.  I now have several Windows 7 64 bit clients, and am
unable to connect them to the shared printers on the server, it
basically indicates that the proper driver was not found.

I've just begun researching this issue, and it looks like I can add 64
bit drivers to the server using Printmanagement.msc via the procedure
described here:

Has anyone done this before, and is there any risk of breaking the
printer connection for my 32 bit clients?
