Homebrew PCBs

I'm printing the same board image, originally from Eagle, now a PDF. I 
was trying scaling with the print dialog to get the dimensions right, 
when I discovered that the size would change without changing the 
scaling. It is only noticeable in the Y dimension, so it could be the 
rollers, page feed mechanism, etc.
