So, the actual page and toner that was listed on the web site were the numbers I needed, however, per this review the numbers are not the same and that corrispondes with the printer not working. These web companies need a person to answer a phone period this BS with no phone calls only email is horrible service

Although not official HP ink, once installed the printer recalibrated and accepted the ink. No noticeable change in print quality. Great price.

Thank you for this terrific product, and the quick turnaround time from ordering date to delivery was much apprecited!

Question: how does one tell which ink cartridge is low. I replaced them all but it doesn’t seem possible that all would go low at the same time

So far, so good. Only time will tell.
