Check out the following program its a command line executable. I recommend adding this to your login script per user via AD Users and Computers. You can change the Bat file i sysol or just search SBS_LOGIN_SCRIPT.BAT.
defprint.exe /d Port_Name ex. IP_1.1.1.22
rename this extention on the attachment to exe and you can use it. If you don't want to use this goto google and type defprint.exe
