I really enjoy printing and binding my own books. It is a fun hobby and useful for creating draft copies of a work in progress. But, when it comes to publishing high-volume professional quality books, it makes more sense to outsource the fulfillment process.
Not long ago outsourcing printing meant ordering thousands of copies of your book at a time and storing them until they were all sold. The process cost lots of money and required you to manage inventory - POD (Print On Demand) publishing changed all of that.
