I was once told the orifice of an inkjet printer is about 25 microns.  The
particle size of the pigments is about 0.1 to 0.25 microns (I think).  I
beleive the print heads and cartridges have screens in them that catch
anything larger than 1 micron.  So, the particles in and of themselves are
probably not going to clog the printer.  It's when the carrier dries out
that the problems come.
