Yes, the two halftoning methods yield nearly identical results.  The nod
would go to accurate.

>From the looks of the image, when printed with the gimp-print 4.2.7
driver, the default contrast of 1.0 is much too high. Unfortunately,
lowering the contrast appropriately (about 0.80 makes the image look
reasonable) also turns any white areas into gray.

Turning the gamma down to about 0.90 make a significant improvement, but
the quality was still much lower than either the ljet or CUPS driver.

I had tried tweaking the gimp-print driver before posting, but I also
didn't feel like using that much toner and paper to fine tune the driver.
