When we bought printer we were told the entire ink system was all one unit. To my surprise I found out separate units. Very easy to remove old snd put in new. The old ink jet was a horror show. I did have to do a bit of fiddling with IPad and printer and reseat it a couple times but finally got it to go.

Having attempted to use other compatible ink cartridges, I found them to be awful, and will continue to use HP products.

As always I expect the best from HP. Their cartridges are more expensive but always work perfectly. Well worth the extra expense

I can count on HP products - they are the best! I never have to worry about refills because they last a long time.

Ease of putting in printer and length of use.

Excellent product but highest price!

Worked out good.

I have been using HP toners for years and the quality of print is amazing and the color is exceptional. In addition, the toner yield for me is at or better than marketed by HP.

Great toner but EXTREAMLY expensive. I piad almost as much for the toner as I did for the laser printer. HP needs to reduce the cost of toner cartridges.

the printer keeps saying toner is low even though i just change the cartridge.
