Hi Christian,
When I have to do something like this, I usually write it in
Postscript using this:

/def mm 2.8346 mul

that converts a dimension in mm to points (1/72 inch). However, this
won't work in R. It may be possible to set up the device like this:

# generate a blank plot
# display lines, etc. in mm with 0,0 at the bottom left

The resulting file should be printable. Warning, I don't have time to
test this right now.
