Print-to-scale ideas

[Jacob Delfos]

Abe,

I've done this in the past. As Steve says, PDF would be safest, because you can control size and resolution. Alternatively, you can take the risk of assuming your clients will print at 96dpi (which most users do, Internet explorer is set up this way by default), and then use a print scale variable which is derived from the normal scale variable (multiply with constant). You could also manually calculate your scale from scratch, by calculating the distance on the ground, and calculating your distance on paper (96 pixels to an inch). But do not assume the 96dpi to always be true.

I'm not sure of the details of how to do this, but I think you best bet
at doing this is with either pdf or postscript. Both of these should
give you the control you need to control the physical size of the image
on the output medium.
