Script to install printer, help!

My company does not use Active Directory. We just put a new printer in, and I want to install the printer by deploying a script through Novell. I have the script pretty much all ready to go, except it has one problem... it makes the printer default on my machine every time I run it. I was wondering if someone could take a look at it and see what I need to do to remove the action of making the printer default.

Here is the script:

CLS
@ECHO off
SET varIP=172.16.20.7
SET varDriver=Xerox WorkCentre 7535 PS
SET varDriverFolder=C:\Xerox\WC7545-7556_PS_x64_Driver.inf
SET varDriverFile=C:\Xerox\WC7545-7556_PS_x64_Driver.inf\x2DNORP.inf
SET varName=Mailroom Xerox 7535
SET varLocation=Mailroom
