11. A method of processing by a host comprising: receiving, by the host, an input document directed to an imaging device; determining, by the host, a set of capabilities associated with the imaging device; determining if the input document is one of the following: an image-only PDF document with at least one embedded PDF image with an embedded PDF image format; and an image document with an image document format; and if the input document is determined as an image-only PDF document then 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, and if the received input document is an encrypted image-only PDF document associated with a set of security information, then if the imaging device is adapted to support a PDF encryption, transmitting to the imaging device the encrypted input document; and if the imaging device is not adapted to support a PDF encryption, then decrypting the received image-only PDF document at the host, and transmitting to the imaging device the decrypted input document; otherwise transmitting to the imaging device the input document for rendering by the imaging device; 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 of the input document, then: transforming, by the host, the at least one embedded PDF image of the input document into a transformed image document with the image document format compatible with the embedded PDF image format of the input document; 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; else, if the input document is determined as an image document then based on the determined set of capabilities, if the imaging device is adapted to support the image document format of the input document, then transmitting, by the host, to the imaging device the input document; otherwise, if the imaging device is not adapted to support the image document format of the input document but adapted to support an alternate image document format which is also adapted to be converted at the host, then: transforming, by the host, the input document to a transformed image document with the alternate image format; and transmitting, by the host, to the imaging device the transformed image document with the alternate image format, for rendering by the imaging device.
13. The method of claim 11 further comprising: if the input document is determined as an image document, then based on the determined set of capabilities, if the imaging device is not adapted to support the image document format of the input document and not adapted to support an alternate image document format which is also adapted to be converted at the host but adapted to support a PDF format with an embedded PDF image format compatible with the image document format of the input document which is also adapted to be converted at the host, then: transforming, by the host, the input document to an embedded PDF image with the embedded PDF image format compatible with the image document format of the input document and coding the embedded PDF image as an image-only PDF document; and transmitting, by the host, to the imaging device the image-only PDF document, for rendering by the imaging device.
