Re: printing

I think the problem with my printing relates to some kind of incorrect
measurement of the printable image size.

I find that (usually) the full height of my image is printed, but only
about 2/3 of the width, with the other 1/3 being clipped. When I get a 1/2
size version of my image, and print that instead, I can see everything -
but of course the image is half the size I want it to be. I can't work out
why it is that I'm not getting the right numbers for my printable image
width. Here's my code. If you can help, thanks!
