I was gong to buy a new printer but I decided I bought new HP genuine black cartridge to fix smeared print outs. This fixed my printout issues they are clear and crisp. I will always buy genuine cartridges you get what you pay for. This was better then buying a new printer or fuses.
This took so long to receive ... I could have gone to a store but the last time they were out or gave me the wrong one. This works well and easy to put in. Just wished they weren’t so expensive.
I have written so many emails and trying to get so much help with my HP 7740. I know nobody reads these things because nobody has ever gotten back to me.
