Missing Home Link on a print-friendly page

Hi,
I have a question about print-friendly page and a Home link. I am looking in the WCAG 2.1 but don't see a clear instruction that this page has to have a home button.

Here is a scenario:

I was looking for an information on the Web and I found a page with a good reference:  "Guideline on Making Information Technology Usable by All<https://www.tbs-sct.gc.ca/pol/doc-eng.aspx?id=32620&section=html> ". I was curious what else is in this guideline, but guess what, the page is missing a home button. Hmm, I looked and looked, and finally it occurred to me that this page is a print only version. Problem is, the page is indexed by the search engine and displays in the search results. Not being able to find the home button, was very, very annoying.

I think there should be at least, a link to the guideline<https://www.tbs-sct.gc.ca/pol/doc-eng.aspx?id=32620> somewhere on the page. But ideally, there should be a home button.

Any advise and a link to a resource will be very welcome.

Thank you,
Martyna
