We have just learned that HP has updated the firmware in their printers that utilize the HP 950 / HP 951 (or HP 950XL / HP 951XL) cartridge models. For printer models released in March 2015 (or later), our HP 950XL / HP 951XL will not be recognized. This affects the following SKUs:
151-590-01CYANNU
151-590-01MAGENTANU
151-590-01YELLOWNU
151-590-STDBLK
151-590-STDCYN
151-590-STDMAG
151-590-STDYEL
151-790-01
If you have purchased your HP printer prior to March 2015, the above SKUs will work just fine. But if your printer was purchased on or after March 1, 2015, it is likely that your printer will not recognize our SKUs (due to the firmware update by HP in its newest printers). We are working on releasing a newer version to support March 2015 or newer printers as soon as possible.
