title: Is there any worldwide on demand photo printing API?
body: <p>I run a website where users can upload art images and photographs. Now, I am looking for a photo printing API to sell printed products to visitors. I want to do this entirely from my own app, under my own domain. Basically, I need something similar to Google Cloud Print, but I really need high quality print products, like large canvases and aluminium prints. This print service would preferably be globally available and at least take care of the actual printing, international shipping and - if I would be really lucky - also customer service. </p>
  
  <p>So far, I have not been very successful, because most print facilities do not have a very user-friendly API and/or require a minimum number of orders that is completely ridiculous. Suggestions are welcome! </p>
