Setting Default Printer by Group Membership

Good day,

I am looking for a way to set users default printers based on their group memberships, which in itself isn't difficult however I have users that are in the same group but not in the same physical location. For example:

Users 1 and 2 are in the east end and members of Group 1, they use Printer 1. User 3 is in the west end and member of Group 1, they use Printer 2. I want Users 1 and 2 to default to Printer 1, but User 3 to default to Printer 2 while being in the same Group.

I would prefer to do this via scripting hence scripting forum.

Thank you.
