Isn’t this just cool?!
The Tattered Cover Book Store, in Denver, Colorado (one of my favorite bookstores) puts on display the newest way to print a book (trade, not hardcover)–the Espresso Book Machine, or EBM! There are many advantages to print-on-demand over the offset-type printing currently used to print books, not the least of which is immediacy, printing when needed, less physical inventory to warehouse, etc., though (to me, anyway) part of the fun of discovering a book is physically browsing the book.
Anywho, neat to watch! Enjoy!
