Thank you guys for all the help in this thread. And @jimbo45, I tried spoofing the computer into thinking a network printer was a local printer, but it didn't work. I am told there is an error on the Epson website that says the printer is XP supported, but it isn't. There are no XP drivers for this printer, and when you download drivers from the XP part of the website, it really just downloads the Win 10 drivers.

I have gone for the ultimate workaround on this, installing a new Win 10 64 bit computer just to run the printer and the order controller, and then setting up a batch of mapped network drives on Win 10 64 that links to all the locations on XP that we obtain files from for printing.
