1. A method of processing by a host comprising the steps of: receiving an image-only PDF document comprising at least one embedded portable document format (PDF) image with an embedded PDF image format, wherein the image-only PDF document is directed to an imaging device; determining a set of capabilities associated with the imaging device; based on the determined set of capabilities, if the imaging device is adapted to support a device-based image-only PDF process adapted to process image-only PDF documents, then transmitting to the imaging device the image-only PDF document for rendering by the imaging device; and otherwise, if the imaging device is not adapted to support the device-based image-only PDF process but adapted to support an image document format compatible with the embedded PDF image format, then performing the following steps: transforming the at least one embedded PDF image of the image-only PDF document into a transformed image document with the image document format compatible with the embedded PDF image format; and transmitting to the imaging device the transformed image document with the image document format compatible with the embedded PDF image format, for rendering by the imaging device.
