Bought this cartridge because apparently there were no standard 232 cartridges available for the 4200, and we print infrequently. When the old one gave up, I put this one in, fresh from the package and correctly. The printer did not recognize it. Can't return it for being ENTIRELY DEFECTIVE because I ordered it before the old cartridge went out. I mean, who waits for their cartridge to go out before ordering a new one?????? SCAM, waste of 20 bucks. I have a thing of ink that I now have to throw away.
Buy the Epson OEM. This is a scam of the worst kind. If you've updated your firmware in the last few years on the printer, RUN AWAY! You're just wasting your money and won't be able to return it.
