Digital BW, The Print

eMail me the square you made, and I'll print it out.  I have a 90x
microscope, as well as an XRite 810 densitometer.  I can tell exactly what
the printer is doing, and I'll let you know.  It will take me a day or so to
do the test.  I happen to have one 3000 setup with Piezo inks, and one 3000
setup with Epson inks, so I can make four test prints.

Pure black should only print using black ink.  Actually, it'll be better, I
think, to do this test using the Epson inks...since you'd see color if the
Piezo driver is in fact using any of the other inks, right?
