One of the main features of piezo head design is how forgiving they are
with ink formulations.
Thermal heads require the ink boils at a certain temperature and
maintains a certain viscosity during the printing process.
Piezo technology is more forgiving because the ink is mechanically
propelled without heating, and the ink nozzles can be considerably
larger then the ink droplet, using the frequency the piezo element is
activated to determine how much ink is released.
Although I don't suggest trying to run ketchup and mustard through them,
as long as the ink is within certain tolerances and of a small enough
particle size, it may well work. Piezo heads are being used for
everything from dye sublimation inks, to solvent inks, to oil based
inks, to conductive inks, to plastics, to food dyes, etc, etc.
So, as to your question, yes, there are dozens of 3rd party ink
formulations that work with Epson printers. SOme work better than
others. Pigmented inks are more abrasive than dye inks, because
pigmented inks are made up of actual particles of colorant kept in
suspension in the carrier agent. Dyes are molecular and are literally
dissolved into the carrier. Over time, therefore, pigmented inks do
wear the heads more than dye inks. For the average piezo inkhead
printer, it is not too significant an issue.
Although I have not looked around, I suspect there are both pigmented
inks being should 3rd party for the R200, and CISs. My only concern is
the CIS is usually costly enough to make it worthwhile to consider if
buying a more robust printer may be worthwhile with a costly investment
of a CIS and bulk inks. It is not that the R200 will product poor
prints, because it doesn't, but it is designed as an economy printer,
and it's cost reflects that. Most people using a CIS print great sums
of prints in a short period and a printer with a higher duty cycle may
be more reliable.
