The number of books you should print depends on several factors. One consideration is the printing process used. Offset printing is uneconomical at quantities below 1,000, so if you are using this printing technology, then it is sensible to print that number at least. It may even be worth printing the industry average of 3,000. This means each book will cost about $1.39 to print.
Digital printing is more economical for short runs, so you can print in multiples of 100 depending on how many you think you might sell. The amount of promotion you will do or the number of sales you have got through pre-publishing promotion will also give you a guide to how many books you might expect to sell. It is best to be realistic about how many books you will sell and how much marketing and promotion you will do.
