Issue
The BarDIMM has been installed on a printer but doesn't load (it is not seen on the configuration page and barcode aren't printed).
In that case, it is possible the option "Skip disk load" has been activated on the printer.
Example of Solution installed but not loaded:
How to fix
You will first need to go into the administrator preboot menu of your HP printer:
> Shut the printer down
> put it on and when the HP logo appears on the screen click on it
In the menu, navigate to the following menu:
> administrator / Startup option
> then uncheck the option "Skip Disk Load"
Come back to the menu and click "continue"
Now the BarDIMM will be launched and the barcode should be printed.
