Installing and updating software, drivers, and firmware
Installing the printer software
Notes:
• The print driver is included in the software installer package.
• For Macintosh computers with macOS version 10.7 or later, you do not need to install the driver to print
on an AirPrint-certified printer. If you want custom printing features, then download the print driver.
1 Obtain a copy of the software installer package.
• From the software CD that came with your printer.
• Go to www.lexmark.com/downloads.
2 Run the installer, and then follow the instructions on the computer screen.
