Is that just because I scanned at 300dpi and my printer is also
300dpi?  Maybe not.

I've been scanning the docs and I'm not getting the -page setting.

    # Looks fine in gv
    convert  1.jpg 2.jpg PS:- | gv -


    # Also looks fine
    convert -page 2400x3100 1.jpg 2.jpg PS:- | gv -

    # This places tiny image in lower left corner of page
    convert -page letter 1.jpg 2.jpg PS:- | gv -

Not sure what "letter" means -- the docs show it as

    Letter        612   792

But the docs say those are DPI not points.  And indeed, these seem the same:

    convert -page letter 1.jpg 2.jpg PS:- | gv -
    convert -page 612x792 1.jpg 2.jpg PS:- | gv -

Maybe I do need to try a newer version of ImageMagic that knows that
"letter" is in points?

What I don't get is how to translate to physical sizes when printed.
Say I have an image of unknown size and I want to display it 4" wide
image centered on the page to be printed.

Can I place two images on the *same* postscript page?  Or would I need
to first create a new single image of the two images?
