Yes, it is really very difficult to imagine a world without printed matter because
(i) Everywhere in our surroundings, we find evidence of print, i.e. in books, journals, newspapers, prints of famous paintings, etc.
(ii) We see printed materials in everyday things like theatre programmes, official circulars, calendars, diaries, advertisements, cinema posters, government notifications etc. (Hi) We read printed literature, see printed images, follow the news through different newspapers and track public debates that appear in print.
We take this world as world of print and often forget that there was a time before the printing technology came.
