Photocopiers can introduce small distortions in the copy.

Some copiers used to routinely shrink the copy 1% or 2%
in one direction.

If you're doing small parts, it probably won't matter.
The bigger the part, the bigger the problem.

If you want to do big parts, you should test the copier
by copying a ruler and seeing how well the copy
compares to the original in both the X- and Y-axis.
Then try to orient all the parts the same way on
the copy so that the distortion is at least consistent.
