Review on 🖨️ GREENBOX Remanufactured Ink Cartridge Set for Epson 273XL 273 T273XL - Compatible with Expression XP-520, XP-820, XP-620, XP-610, XP-800, XP-810 Printers (2 Black, 1 Photo Black, 1 Cyan, 1 Magenta, 1 Yellow) by Shawn Jacobs

Not sure if they are really compatible. The printer (XP-820) complains that these are not Epson cartridges, which is what I expected, but now starting a new job is becoming problematic. The printer goes offline and does not restart. I think this is because the drivers detect incompatible cartridges and turn off the printer between jobs. It will not activate for a new job unless you physically turn the printer off and back on between uses.
