Digital BW, The Print

I'd like to echo Paul's comments. Don't let concerns about
blockage put you off MIS inks. Since I switched to filling
my own MIS cartridges, I've had no trouble with blockages.
I just run a cleaning cycle when I haven't used the printer
for a few weeks. And since the ink costs much less than the
comparable Epson inks (UT7 is less than a quarter of the price of 
K3, for example), the cleaning cycles don't trouble me.
Filling your own cartridges is very easy, and I recommend it
highly.
