I'm using a TSC ME240 thermal printer. My print sizes are 48,3mm x 139,7mm. My printer configuration show this value.

However, when it comes to Firefox, the printing window is displaying 47,5mm x 139,00mm. I can manually change it but the value get restored to 47,5mm x 139,00mm every time I launch a new print.

Same problems happen to all of my clients and it's a big problem.

Thanks for helping.
