Unfortunately, or perhaps fortunately, your typical wide format printer is not a device known to XP or any other flavor of
Windows. It's not configured as Yet Another peripheral connected to the
computer. This printer must be completely driven by it's very own and very specialized software. It does not present a general interface and driver for
windows to access, such as a LaserJet or some other desktop gadget does.
That being the case, only software capable of driving both your printer and it's interface, whatever that might be, can make the thing work. It's the reason you can't print to it directly out of Illustrator, Word, Excel or any other package that supports printing. The device simply doesn't exist to any of these packages.
