EPSON 812 DURABrite Ultra Ink High Capacity Magenta Cartridge (T812XL320-S) Works with WorkForce Pro WF-7310 ,7820, 7840, EC-C7000

These are expensive and getting harder to find at a discount. OEM and as advertised. The last time I purchased I had to order through Epsom because everyone was out of stock.

Works as it should. I wish the yield was more, but whatever.

Easy to order and easy to set up. Ink quality is very good. It’s a good value for money if you use a lot for one month or few for 3 months.

Perfect

I like that these offer the inks in different cartridges. That makes it easy to swap out only what you need. I don't like that Epson keeps messing with the firmware to invalidate third party cartridges. Yes, you can use them, but it's often a fight. This will be the most convenient option, being first-party. I like how long this one lasts. I go through a lot of printouts, mostly 11 x 17 inch maps, and I can get a few hundred prints to a refill.

Expensive, but works every time and never any issues with ink leaking or the printer not recognizing it. I like how long it lasts.

Great Ink

Positive feedback

I will never buy this product ever, no sufficient ink in the cartridges. The Epson WF-7310 is the worst printer you will ever buy, it costs C$800+ for ink cartridges to print 350 sheets of 11" x 17". The printer uses original ink cartridges from Epson, you can only buy the ink cartridges from Epson site or from Amazon site. I will never or not buy the printer or any Epson printers with ink cartridges again, I will not recommend this cartridge or Epson WF-7310 printer(s). The Epson Customer Support/Service is non supportive.
