HP M4xx Printers introduced after January 1st, 2021 use a new operating system and require new USB sticks compared to previous HP printers, part number JM30100Z, its color is white.
The list of hp Printer models requiring that nano USB stick are defined here:
https://www.bardimm.com/bardimm-pro-for-hp-printers.html
Printer models supporting the JM30100Z that have ‘4’ as their model first number digit (i.e. LaserJet 480ef) have no embedded USB port, the external USB.
The BarDIMM Pro USB stick JM30100Z needs to be installed on an external USB ports of the printer.
• There is a USB port on the back for both MFPs and Single Function Printers, and another one on the front of MFPs, either one can be used.
• The BarDIMM Pro USB stick needs to stay there permanently.
• BarDIMM Pro part number JM30100Z is a nano USB stick
designed for such installation.
• Remove the plastic cap protecting the USB connector
• The “HP FSM” engraved on the metal connector indicates the stick is for “HP Futuresmart Modern” generation (models released after January 2021).
On supported M4XX printers:
• Locate the USB port you want to use,
in that example the rear USB port on a M480ef
• Insert the USB stick in the USB connector
• Reboot the printer
• Important: keep the USB stick in the USB connector otherwise BarDIMM will display “DEMO”
across pages that contain barcodes.
