Most anti-freeze is still ethylene glycol, although the low toxicity
propylene is now being distributed. Propylene glycol is used as an
emulsifier and smoothing agent in foods.

Once again your ignorance of all things Epson shows ... you never have
to "change the black ink type" in the 4000 because it has both Photo
black and Matte black available at all times, switching between them as
required based on the chosen paper type. You are confusing that model
with others that only have a slot for one black cart at a time.
>That's a LOT of ink going down the drain
I've owned a 4000 for going on two years and never had to change the
waste tank ... you are confused.

Propylene glycol is the standard for inks. Non toxic, sometimes
found in foods; it keeps chocolate chip cookies moist after months
of sitting on the grocery store shelf.

Actually, there is no problem with my 1270. To the contrary, it has never
clogged in over 6 years, which is why I mentioned it in this thread.
Perhaps you missed that part...

California's lame answer to this was to start slapping people with disposal
taxes when they purchase monitors and the like. Stupid part is...they give
no indication of any particular mechanism this money creates for the actual

It kills me too, except that I then remind myself of all I couldn't have
done without it at the time.
It's sort of like gasoline. You can look back at all the gas you've burned
over the years...having nothing to show for it...but the alternative would
have been going nowhere all those years. :)
Wasted money? Nah. Really just money spent to get where we're going...both
on the road, and on the computer.
(But OK...on the other hand...it still is a little depressing!)
