HP Printers introduced after January 1st, 2015 and before January 1st, 2021 can use solutions stored on USB sticks. The BarDIMM solution for those printers is delivered on a violet USB stick and have the part number JM30100F or JM30100X (JM30100F+cables).
The list of models that support it is available here:

If the printer is equipped with the optional HP option kit B5L28A – Two-Internal USB Ports for Solutions, refer to chapter 3.1.2 as you just need to insert the BarDIMM Pro USB stick directly in one of the two USB slots.
If the printer is not equipped with the optional HP option kit B5L28A – Two-Internal USB Ports for Solutions, you need the BarDIMM Pro part number JM30100X, it includes two special cables that allows to connect the USB stick to the printer controller board.
When using the JM30100X special cable, the printer/MFP front panel walkup USB port is deactivated and cannot be used. If you need to use the front panel USB female plug to let users walk to the device with documents to print on USB stick, you must purchase and install the optional HP option kit B5L28A on which you can plug directly the BarDIMM Pro USB stick.
Installation procedure:
• Switch off the printer and unplug the power cable from the wall.
• Open the printer formatter like to install extra memory. Please refer to your printer manual as the procedure differs between printer models.
• Locate the USB cable with the micro USB, the one in the center.
• Unplug the USB cable from the micro USB board connector.
• Connect the BarDIMM Pro cable micro USB male plug to the printer board micro USB female plug. Only one of cable A and cable B will fit thanks to its angle, you can discard the other cable.
• Connect the BarDIMM USB stick to the cable female full-size USB plug
• Close the formatter, connect the power and network cables back and switch on the printer.
The plug of the micro USB male plug disconnected from the print board (and replaced with the BarDIMM USB cable plug) must be secured away from that same circuit board so that there is absolutely no risk of contact, it could damage the printer. We recommend to apply plastic adhesive tape around that micro USB male plug metallic part for a maximum safety if needed.
If you are not sure about how to do that we recommend you acquire and install the HP USB Kit B5L28A instead of using the BarDIMM USB cable and connect the BarDIMM USB stick to that kit USB plugs
