Sometimes you want a hard copy!
Jane Ross, (Apple Distinguished Educator), has been making printed versions of files made with Book Creator on an iPad for many years. The app produces a really decent file for hard copy printing...What you do get is a paper book which looks like it was purchased from a bookstore – it looks so professional. [She explains] the steps that she uses to create a file that will be 'print ready'. "
You can also send the finished PDF file to any number of online book printers. (Blurb, lulu, snapfish, mixbook, mypublisher and others.)
