print queue for pc on mac server

We have offices that are primarily Mac with MacMini Servers that host our printers. They do a great job managing the print queues and centralizing the necessary drivers but we are unable to connect our PCs to them. Instead we install the drivers and connect them to the printers manually on the PCs. We would love to be able to host both mac and pc drivers from the Mac Servers so that we don't have to get a separate PC server just to handle a few printers for a few PC users. Any ideas would be great! Thanks.
