Yes, that's an important point. I rotate one of the images 180
degrees for that very reason. This especially important if you are
panelizing (multiple boards in a single image).
Its a good idea to print a test image to see where the distortions
are. I use a copier so I just copied a piece of graph paper and found
some small distortion at one end of my copier. I avoid that area.
Also, humidity is an issue to consider since the paper can shrink when
subjected to the fuser heat. You might try running the paper through
a blank print cycle to dry it but use it quickly before it reabsorbs
the moisture.
