To start you have to make your Script into a PDF File. on order to that you should be able to convert the file while saving it to your computer.
Once you have a PDF of your Script, you can go to Barns And Nobel Press and make an account.
Then, you select what you want it too look like, You select "create book", select print, make a title, and select, "keep it personal". Then you choose your estimated page count I picked 51-100, then you select page size, I chose 8.5 X 5.5 size, then it prompts you to choose, interior print color, cover format, cover finish, and paper color. If you put pictures inside your script I suggest choosing standard color, hardcovers last longer, so if you have more of a budget, I would choose that, and I also recommend a gloss finish and white (70lb) paper color.
Once you choose all this it will tell you the "Printing Costs per book" (before tax and shipping). Mine came to $9.16 CAD
Click, save and continue, and then it will prompt you to start setting your book up. You can then set your desired formatting, it does do an auto set-up so if you don't know what you want, or like the standard format, it sets that up. Then it will prompt you to prepare your images, they recommend that you use high resolution images (at least 300 DPI) for crisp-looking graphics. Then, it reminds you to "embed you fonts" on your PDF file, if you didn't, or don't know how, it gives a demonstration on how to do that. They recommend that you use Microsoft Word, or MAC Pages.
Once you know you are ready, It prompts you to upload your interior files. It will upload it all on the screen and then you should, confirm that you have uploaded the correct file, make sure that all text is within the margin regions, check that your page numbers, footers, and headers are within the margin lines, confirm that your fonts appear as expected.
Then you will get a prompt to prepare the cover. You should have your images ready, they show you the process, and walk you through what to do, once you are satisfied with the cover pictures. You can save it all and check out, it will calculate shipping and taxes.
Then, BOOM! your script is a book!
