How do I install the printer driver on a Macintosh using a USB cable?

Double-click the Printer Driver Installer icon and follow the instructions on the screen, then make sure the printer power switch is on. Connect the USB interface cable to your Macintosh and then connect it to the printer, then open the Chooser from the Apple menu and click the HL-1650/1670N icon to select it. Note that you should start installing the driver before connecting the USB interface cable to the printer. (Page 2)
