Print on-demand (POD) is a type of order fulfillment where documents are printed only when, and as soon as, an order is placed. With POD technology, you can print in single or small quantities, rather than pre-printing materials in bulk. There are no minimum order requirements. The main benefit of POD is the ability to print the exact number of documents you need, when you need them, reducing costs and eliminating waste from unused, excess documents. In addition, POD lets you personalize documents via variable data printing (VDP). VDP allows for customization of elements, such as text, graphics, and images, from one printed piece to the next.
