I use a Canon i850 printer to run off the material I gather from APUG and the web. My problem is the high cost of Canon ink cartridges.
My printer is set to "greyscale" which helps a bit.
Has anyone had success with the ink refill centers which will do a single unit for 1/3 the cost of a replacement. Most important is will the refill nullify the extended warranty I have on my printer?
Thanks in advance,
