Printing from office laptop on my home network

I have a home network with 5 PC’s networked to a brand new Mac. Printer is on the Mac, and all 5 PC’s print to it fine (took some doing, but it works). But I also want to use my Windows XP laptop from the office while I’m at home, and use the same printer. The laptop is set up for our domain at the office, and I use a vpn to connect to the office from home. Does anyone know how to do this?

Thanks!
