Abstract
In the embodiments described herein, partially encrypted print jobs are described which include unencrypted print job commands and encrypted print data objects. One embodiment comprises a print controller that includes a memory and at least one processor. The memory stores a print job comprising one or more print data objects, and print job commands that define data boundaries in the print job for the print data objects. The at least one processor processes the print job commands to identify the print data objects for the print job based on the data boundaries, encrypts the print data objects using a key while the print job commands remain unencrypted, generates a partially encrypted print job comprising the encrypted print data objects and the unencrypted print job commands, and provides the partially encrypted print job.
