Here's what worked for me:
Open the graphic in Photoshop (or whatever) and get info on the image size. You'll get pixels, size and DPI. You'll see that the DPI on most of the templates is 72 DPI, which is screen resolution. The number of pixels is right, it's just that the DPI is wrong. One of the templates printed out perfectly without any tinkering, and interestingly enough, its DPI was 125.
Change the DPI to 125, and your templates will print correctly. ...at least mine did. (Obligatory caveat, I did all this on a Mac, but it should be the same on the PC.)
HTH,
