Larger font or digital book?

The font size in the published book is very small and many of my students complain that they are unable to read it because of the size, color of the font, and background page colors. Is there any plan on offering either a larger print book or a digital version so that individuals with issues reading the small font can have an alternative? Sorry if this was asked in the past, appreciate any feedback on how to help make accommodations for some of my students.

The book's text is published under a Creative Commons license, and you can find this online in digital form provided by 3rd parties. When the subject came up a while back here on the forum, the content people discovered was based on older versions of the book, so certainly not so good as an official offering, but probably still better than nothing.
