In theory the following should work, but see my problem below.
When using the display utility, as Matt described, before you print,
click on View | Resize The dialog will show the existing geometry eg
640x480,0,0 Replace this with the number if pixels needed to fill the
narrowest width of your page. For example, if your printer is looking
for 300 dpi and you have 8inch X 10.5 inch printable area, the narrow
direction is 2400 dpi so you would use 2400x2400. The "Constrain Ratio"
checkbox is ticked by default so your resized image will be some
different size with a max of 2400
Then do the File | Print sequence.
I tried testing this and it works to a point. A small crop expands a
larger box size, but not full width. My printer is a HP 950c using
and my box uses CUPS to print to it. The IM display command prints to a
postscript printer. I'm not sure what is going on with my setup and I
don't have time to dig into it. (Nor do I have any idea where I would look!)
