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.
