The Brother HL 2270DW printer driver is a software program that converts the data you wish to print into a format that the printer can understand. Without the printer driver, you will be not able to perform any printer related operations. After setting up the printer, download the print driver from the official site. Usually, the printer driver software (installation CD) is enclosed along with the printer during the first time purchase. Connect the Brother HL 2270DW printer to your computer through a wired or wireless network and start the installation process. As soon as you open the driver file, the installation process begins automatically. After the installation process, try a test print to verify the setup.
