Abstract
Systems and methods are provided for piecewise encryption of Page Description Language (PDL) print jobs. One embodiment is a method that includes receiving a Page Description Language (PDL) print job at a printer, wherein the print job includes segments of PDL content, and includes unencrypted PDL content. For each of the segments within the print job, the method includes detecting an identifier (ID) for the segment, correlating the ID with an encryption key stored at the printer, and decrypting the segment at the printer via the encryption key. The method further includes printing the print job, including each segment that has been decrypted.
