The cartridge arrived in record time, but it still is creating "gaps" on the printed copy, which has been the problem since last summer with a brand new printer.
The cartridges are easy to install and perform very well. I do have two concerns. One is that I paid less for my first car than one of these cartridges costs. They are very expensive. Secondly, my HP printer now seems to be telling my computer that there is some problem with the printer. Installing the cartridge is so easy, I don't think I caused a problem. Could it be that there is a flaw in the cartridge that causes the error message?
