Probable bug in lp? I did

	hget ... | jpg -9 | lp -dstdout -pp9bitpost > ... # this is a school  
project
	hget | lp -dstdout -pjpgpost > ... # when I realized it existed

However, there is one GIF in my project and that didn't cause any  
problems, so it makes me wonder...

The only postscript I know is the color changing code (which I learned  
from your talk slides); this problem confused me.
