I have been using HP ink for the past 5 years. The product always does a great job, the colors are vibrant and I can count of the product to produce a good print out.
I ordered two ink cartridges online. The cartridges came very quickly. They also came with a bag to use for the return of old cartridges. This is all very simple. I followed the directions for installation of cartridge from the little how-to video built into the printer. The only difficult part was removing the plastic cover for the ink. I am sure it will be easier next time, now that I know how much pressure to apply.
This is the first time I have tried to use cartridge. Just to set alignment, ink level come down to 3/4 of initial level. BLACK ink don’t working even for a single dot.
