I used the following syntax to show and print the image:

+verbatim-
imshow (uint8 (floor (255*rand (200,200,3))))
print /tmp/foo.pdf
-verbatim-

The image appears correctly on-screen but whatever the chosen output format (here pdf) the image appears completely black in the printout.

I'll attach a patch when I have a bug number.
