Digital BW, The Print

As someone who spent a little effort reverse-engineering the commands sent
by the Epson printer driver (perversely, not to find out how to dither, but
how to send commands to the printer directly - was trying to figure out if
the clean cycle could be done on one print-head only. I think I found out
it's under firmware control :)

I do not yet have v6 installed... but I can tell you that the 'progressive'
development of the image is present on an 1160 in the v5.x driver - so I
guess I had assumed it was a feature of the software. Perhaps it wasn't on
the 3000, either because it came first, or because some feature did not
exist in Epson 3000 firmware, and the majorly successful 5.x upgrade for the
3000 in fact had to implement the missing firmware feature in software????

It's semantics again... but unless v6 surprises me, I am fairly certain that
it really is true - this control is coming from the Piezo driver - utilising
features in the printer firmware for sure - but very, very much decided by
the plugin. All a gut feeling mixed in with a little tinkering at the
beginning of the year.
