iPhoto’s Print command is alive and well when you’re in book view: you can print some or all of your book for proofreading or to bind it yourself.
Printing the entire book. Choose File > Print and set the Pages pop-up menu to All.
Printing a specific page. Want to print just one page of a book? Choose File > Print and then choose Single from the Pages pop-up menu and enter the page number in the text box. (A preview appears below the text box.)
To print a range of pages, set the Pages pop-up menu to Range and type the beginning and ending page number in the text boxes that appear.
