Denn,...it's so strange
Pixel Dimensions 264 x 400
Doc. size 264 x 400 inches
Res. 1 pixel/inch
I don't think I've ever seen that before, why is the picture so big and only one pixel per inch??.... yet it's printing small.

It's easy; just lets look at equivalent sizes. If we raise the resolution to our screen resolution of say 72 dots/pixels per inch, then we must divide the size by 72 (remember doing this in maths at school) - so 264 inch divided by 72 equals 3.6: if your screen resolution is 90 then it is 2.9 inch.
This all comes back to an old maxim of mine that when it comes to the information contained in an image I don't worry about resolution but I do worry about actual pixel dimensions:
You can have a resolution of 1000 dots/pixels per inch, but if the image is only 1 inch across it will not contain the same amount of information that a 100 dots/pixels per inch image will if that image is 20 inches across (maths tells us that it will contain half the information).
Hope this doesn't confuse you,
