Yahoo's Flickr, an online community site and photo service, is readying to launch a print-on-demand service, internetnews.com reports; it has also learned that Flickr will partner with Qoop, which has not yet itself launched, to offer the service that allows users to select photos and formats to be printed into bound books. Those who want to publish such books with Qoop technology will be able to sell them on their own websites or through online ads, including a link that takes the buyer to Qoop for payment processing, ordering and fulfillment.
