Photoshop elements dialogue print box too big

What is your monitor resolution? I have seen people have this same problem, just because they have their monitor set to 800 x 600, and the dialog box needs to be 1024 x 768. We upgraded our shop production software, and I had to go to every "thin client" computer on the shop floor to change the default resolution. The new software wouldn't fit on 800 x 600, but it would on 1024 x 768.
Or maybe your dock is just in the way? You can hide it or put it on the side of the screen instead of the bottom. I've seen that problem as well. Under the "apple logo" menu, and select "turn magnification on" or "position on left"
