NOT demonstrated by your test pattern, that is not halftone.  The context
was halftone...not just black ink.

The fact is, when halftoning with the Epson driver and only one ink, it
takes up 16x more space to produce the same tones...given that, it would
only make sense that it has to limit the input resolution WHEN DOING
DITHERING/HALFTONING.

IMAGES?  As in, grayscale or black/white (typically called lineart) only?
Printed with quad tone inks and the Epson driver, or just the black ink?

If you are basing this conclusion on the test image that you posted, your
conclusion is erroneous.
