On October 20, 2022, HP released the latest firmware (the latest firmware numbers: 20221010 and 20221018) which upgraded the HP CF500 series color printers. 

The firmware upgrade caused the prompts to display on the screen of printers with the new firmware version (see figures 1 and 2) .

Note: the Canon printers that use the same technology are not impacted by this upgrade.
