And it's book stores that have to buy the machine, which just changes the whole cost structure.
And printing doesn't have to be more expensive than you want it to be.
PrintingPrinting your own books is undeniably the most expensive option in publishing; ebooks have only nominal cost, and those are per book sold, and publishing traditionally costs nothing in terms of actual money.
But printing your own books doesn't have to break the bank. Stay away from vanity presses, that charge a lump sum and then are POD or make you jump through hoops for reprinting. Find an actual printer, like
Island Blue. They do nothing but print your books. If you're able to go in to your printer, sometimes they will have lists of local editors and graphic artists looking for work, but the printer does not have any business contract with them.
How it works is you format your manuscript properly, then send it to their FTP. It prints, and you pay them. Very simple. Island Blue in particular does an excellent job; they use bright white paper, and have environmentally friendly options. This is contrast to some paperbacks, where the paper is a little yellow even when it's brand new. Paper matters, so make sure you talk to your printer about the best options.
Payment is on a per-book basis, with price breaks at 250, 500, and 1000. But you can order as few as you like, and then order more printed as you sellout of the ones you have, and a lot of printers will give you the price break when you hit the total number of books. Like, if you only want to print lots of 50, because you're not sure how fast it'll fly off the shelves, with a lot of printers you can work it out so that on your fifth order of fifty (when the total of books ever is 250), they will give you the price break, and continue giving you the lower price on subsequent orders.
And, unlike a vanity press, a printer will never claim any kind of publishing rights for your book. You can up and go to another printer if you find a cheaper one; there is no contract.
