Has it been confirmed that this is true?

To date all success has been achieved with the Epson because of the
pigment inks.

Some Canon have a black pigment ink and use dye ink for the colors. I
have been thinking for a while that it may be possible to have  direct
to PCB printing from a Canon if it is a model that uses pigment ink in
the black tank. 

I'm assuming that the Pigment ink is launched by a thermal head. If so
then the initial statement needs qualifying. 

Has anyone done any experimenting with Canon pigment headed printers?
