I don't know that I want to call this a bug - perhaps it's just
a SIDE EFFECT.

If you print the picture "Lady" from the Digipaint distribution
disk (it's a 320x400 HAM mode monochrome image) as a 3 inch wide
image, using halftone shading, under the EpsonX driver in 1.3,
then in densities 3, 5, and 6 (the ones which can not print
consecutive horizontal dots), her lips vanish.

Really.  All of the picture comes out beautifully except the
chin is washed out, and the lips vanish.  My best guess is that
the restriction on horizontal dots causes a severe reduction in
contrast at the darker gray levels.  Thus making these density
modes useless for most gray scale dumps as well as for fine detail.
Oh well.  Someone from Commodore already mentioned that this limitation
probably won't be fixed in software because it's not Commodore's 
problem.  Besides, waiting for a six-pass screen dump to finish 
would cause nervous breakdowns.
