Firstly, I suggest you check if the printer is connected and if you have its latest drivers. If yes, try to reset it using the official manual. If this doesn't help, remove WinMax 2000 Gestão Comercial from your computer (Control Panel > Uninstall a program) and install it again. If you still can't print, contact the support team using
