I don't have any experience with the software in question, but in an absolute worst case scenario, you can run a virtual machine on your computer - VMWare Player is, I understand, free for non-commerical use, there's also VBox from Oracle but I don't know if that works on Windows, and IIRC the free version doesn't let you use the USB ports.
Microsoft have basically given up licencing Windows XP, so you can either use an existing CD & product code, or download one of the many "ripped" versions (beware of viruses!) and use those. Then run the software on the virtual machine. You'll have access to your printers, screen, USB (with VMWare anyway) etc., and you can deliberately set the virtual machine to NOT use all the resources of the host computer, meaning you can minimise it out of the way and get on with other stuff too.
