Hellow, to find where the Brother HL-4070CDW printer driver is located, the most promising possibility was to download "Driver Identifier" from www.driveridentifier.com free of charge. But the program did not install in my computer and unable to find it after all. The reason I need to locate it exactly where is because you can manage to print it Color or Mono depending on document, as well as enhance the color configuration of the printer. Any good advice?
