George Kerscher  coined the term "print disabled" (circa 1988-1989) to describe persons who could not access print.
The definition is as follows:
print disabled, noun; print-disabled, adjective.
A person who cannot effectively read print because of a visual, physical, perceptual, developmental, cognitive, or learning disability.
When used as an adjective, the word should be hyphenated, e.g. print-disabled person.
(outdated) The Higher Education Opportunity Act defines “print disabled” as “a student with a disability who experiences barriers to accessing instructional material in non-specialized formats, including an individual described in Title 17 of the Copyright Act.”
The Google Library Project Settlement defines “print disabled” as “User is unable to read standard printed material due to blindness, visual disability, physical limitations, organic dysfunction or dyslexia.”
