how to install canon pro 100 printer. I have software

Here is an Apple article with instructions on how to setup a printer with macOS. Most times you don't need to worry about any software/drivers from the manufacturer since macOS will usually download the necessary software automatically. If the printer is an older model, then perhaps you may need to use the manufacturer supplied printer software.

Hi there, rosepaul12,. maybe I can help you. Usually you download printer software from the maker's web page, under support.

but seeing as how you already have the software for it, installation couldn't be easier. It should be in the form of .zip or .dmg. double clicking on it will unzip it or mount the .dmg file, and it will appear on your desktop and lead you through the installation process. It will ask you if you want to install software, and you say "Yes" or click on "OK" and then continue, and that's it and it will tell you when it's done
