Canon Mx420 Driver – A Canon driver is a software program that helps your computer communicate with your Canon printer or scanner. If you have a Canon printer or scanner, you will need to install a Canon driver on your computer in order to use it.
There are two ways to install a Canon driver: using the installation CD that came with your printer or scanner, or downloading the driver from the Canon website. If you are installing the driver from the CD, simply insert the CD into your computer and follow the prompts. If you are downloading the driver from the Canon website, you will need to select your operating system and then click on the “Download” button. Once the file has downloaded, double-click on it and follow the prompts to install it.
Once the driver is installed, you should be able to use your Canon printer or scanner without any problems.
