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.

I have not had any problems with print quality using authentic HP toner. The cartridges last a long time and I print out a lot of color documents that look great.

HP 206X Hi Yld Yellow, Magenta, Cyan and Black Toner Cartridges are excellent and easy to install. Print quality from my HP Laser Jet Printer with these cartridges is very good.

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.

Excellent product but highest price!

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.

HP toner cartridges are good quality, are easy to replace and this order arrived quickly - arrived ahead of estimated time. While it's unlikely that I would ever use third party cartridges, I still feel that I'm still paying too much.

The toner cartridge appears to work well but it is very expensive. A set of cartridges for my quality laser printer cost more than I paid for the printer.
