I had a similar problem and incidentally get ride of it when changed the
resolution for print quality - in page setup; going back to a lower
resolution, like 300 or 600 dpi prove to be enough for avoiding distortion.
Hope it helps.

I am trying to print a chart to PDF but the sizes of the graph gets distorted
in the process. The graph is rather large in excel, crossing several pages.
Does anyone know how to keep the original size in PDF format?
