Out of interest, which printer model is this?
I've not used XPM fully yet myself, but from what I understand you can just use the 32-bit version of XP and install the 32 bit drivers for it. However, I don't know if you could print easily from within Windows 7... but you can probably set up printer sharing and do it that way - I've not tried this myself yet, but I don't see why you can't.
You should be able to download it later on today from:

It has been leaked already though if you want to download it elsewhere.
