Yes indeed, this time I get output of about the right size but it looks very
garbled. I've scanned the output of 720 DPI Softweave mode, which you will
find at http://home.swipnet.se/consultron/scan1.gif (96 kB). The black ink has
bled through my inkjet paper. Also, the printer made some strange noises when
printing this - a quiet but noticable "whooshing" sound from time to time.

Setting MODEL_HASBLACK_NO without applying your modifications above did 
nothing, I still got paper feeds. Setting MODEL_HASBLACK_NO with the above
changes gave me rows of color each with different distances of each other
but never less than 0.5 inch apart.
