When printing any pages from Firefox, that contain PNG's with Alpha transparency, or GIF images with transparency, they print incorrectly.

GIF images, print "white" where they should be transparent (print a GIF with transparency over a colored background to see).

PNG images, print "black" where they should be transparent (or semi-trans) (print a PNG with a alpha transparency over a white/light colored background to see).

Reproducible: Always

Steps to Reproduce:
1. Print page(s) as described in the details above
Actual Results:  
Transparent portions of images print either white or black, instead of transparent.

Expected Results:  
Should print as rendered on screen, with transparency.
