What is web to print?

Wikipedia: Web to print, also known as Web2Print, W2P, or remote publishing, is a commercial prepress process that bridges the gap between digital content online and commercial print production. This process allows a print house, a client, and possibly a graphic designer to create, edit, and approve computer-based online templates during the prepress phase. This process increasingly calls for a Portable Document Format (PDF) workflow environment with output provided by digital printing; although there is certainly no requirement that fulfillment be accomplished using digital-production equipment; Web to print is also used today by printers with offset only or both offset and digital-production facilities.
