Robert,
Remote printing is pretty easy to set up. You can either use printers that support IPP (Internet Print Protocol) and route port 631 through your router to the printer or have your remote computer share the printer on the VPN, and have the computer back at the main office running MS server print to that printer.
In our office our servers are running Linux, and we route port 631 to our linux server, running a print server, that allows us multiple remote printers between offices. The linux server handles forwarding the print job to the appropriate printer on the internal network.
