IPAQ (Legacy-Free)

I have several customers that have Compaq Legacy-Free’s which only have USB ports, they want to purchase printers that can print locally but as far as I know Dos does not support USB nor is there a way to capture a USB port or is there a way??? Theyare running WIN2000 Professional, and of course Compaq and any Equipment company where no help. I believe it is possible with Window ME because it uses Legacy drivers but what about WIN2000 Professional??? Thanks in advance…
