Below are two options you can use to print your Canvas course syllabus.
METHOD 1
Install the browser extension Print Friendly and PDF.
Load your Syllabus page and click the extension icon in your browser. This strips out a lot of formatting and makes the syllabus easy to save as a pdf.
METHOD 2
If you wish to keep the formatting, you can simply print the syllabus page. Canvas strips out the navigation menus.
Choose to print as a pdf and be sure to choose the option to remove headers and footers.

This method looks a little nicer, but page breaks can sometimes occur in awkward spots
