1. A method of processing by a host comprising: receiving, by the host, 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, by the host, 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: transforming, by the host, 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, by the host, 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.
