Hi Dennis,
Several methods here...
One explained here :

More here in French (google..)
http://www.retroplane.net/forum/viewtopic.php?t=81Same thing, but from a laser print and then an iron. That transfer the carbon on the wood (but same, you need to make copies of the parts you want to transfer...)
And I use none of them! I use a pin to mark the parts on the wood, then, you have to trace all the lines. Time consuming, but works great.
A little tip, useful for the ribs etc etc, is that once I have all the parts drawn on the wood, I glue another sheet below it with 2 or 3 drops of CA, and cut them on the fret saw... 2 parts are cut at the same time.
For the copies, I can do a copy, no problem. Save it as PDF, jpeg etc etc.
The copier have an enlarge function, up to A0, but not too sure how that would work to scan only one part to enlarge them if you want 4 A0! :?:
