I have ordered from 1Ink.com for a couple of years, and have thought it is my KODAK esp3250 printer issue with the drivers. NOPE, it's the ink! All drivers are updated and yesterday (3/6/14) and put in a new Black Cartridge (the old one was 3/4 full. The New Black cartridge, did not work, *as the 3/4 full cartridge did not work) ran all of the requested checks (Printing) nothing! I have thrown away more cartridges than I've been able to use. NO MORE ORDERS TO THEM! Am I angry "OH YES!" Researching online for a BETTER CHOICE!
