Hello everyone, Has anyone been able to upgrade a Lexmark printer firmware via USB in Linux? I am using an MS310d. Lexmark has a windows firmware update utility but it doesn't detect the printer under WINE. Printing workers ok with CUPS but the firmware update promises to fix some errors that I've noticed. Thanks, Alex
