Fonts may be used in commercial printed books?

May the fonts files be used for printed publications?

The Material Symbols fonts are licensed under Apache v2.0.
This is one of the same licenses used in some Google Fonts.
I think you will find the answer to your question as the second item in the Google Fonts FAQ: https://developers.google.com/fonts/faq

Thanks Thomas! I reviewed it in advance to my post here, and I couldn't find any explicit reference to "printed materials" for the use in a PDF or electronic document, in the Apache v2.0 license... Probably It's covered, because it seems to be very wide... But I want to make sure we will be full covered by that license...

Seems obvious to me, but I am not a lawyer, nor am I speaking for Google in interpreting their license.

I will just note that as the Apache license was originally developed for software in general, not specifically for fonts, that is why it is not completely explicit on this point.

This discussion on Quora covers the same question, I think: https://www.quora.com/What-does-it-mean-for-any-font-to-have-an-Apache-2-0-license-Does-that-mean-I-can-use-that-font-freely-for-commercial-purposes
