Digital BW, The Print

place as much as 96 pl (in 3 pl steps!!!) - not the eject the
smallest drop. It is a problem of max. density you may print out.

Epson heads use variable size drops - the largest drops are about
22
pl. If you use ONLY 4 pl drops you need 5.5 times faster printing
(resolution, nozzles, ...) to put the same amount of ink on
paper.
And rich the same density.

So 512 nozzles per ink with fix drop size 4 pl are comparable
with 96
nozzles with variable size dot technology.<


And Canon hasn't variable droplet sizes yet ?  Seems unlikely.
