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.

Print job security for error analysis

System and methods for page alignment for tractorless paper. In one embodiment, an apparatus receives a print job to be printed on a continuous web of print media in a duplex format with multiple first pages across a front of the web and multiple second pages across a back of the web which correspond with the multiple first pages. The apparatus maps pages to sheetlet regions, and applies first offsets to the sheetlet regions on the front of the virtual continuous forms based on operator input. The controller also determines second offsets for the sheetlet regions on the back of the virtual continuous forms based on an additive inverse of the first offsets, and modifies processing of the print job by applying the second offsets to the sheetlet region on the back of the virtual continuous forms to maintain alignment of front pages and back pages across the web.

Page alignment for tractorless paper

Print jobs may include errors, which may be difficult to resolve. In the embodiments described herein, data objects in print jobs are converted into printable features that show the underlying information in the print job, which allows for a visual inspection of the logical structures and relationships between the logical structures and print data objects in a printed output. One embodiment comprises a print controller that stores a first print job comprising one or more data objects, and print job commands that define the data objects for the first print job. The print controller processes the print job commands to identify the data objects for the first print job, and outlines and presentation positions specified for the data objects, and generates a second print job that graphically represents the outlines and the presentation positions of the data objects as graphical shapes, and provides the second print job.

Print job analysis

One embodiment comprises a print controller that stores a first print job comprising print data objects and print job commands, processes the print job commands to identify the print data objects for the first print job, selects a subset of the print data objects for processing, and encrypts the subset of the print data objects using a key while the print data objects not selected for processing and the print job commands remain unencrypted, identifies outlines and presentation positions specified for the subset of the print data objects, and generates one or more auxiliary print data objects that graphically represent the outlines and the presentation positions of the subset of the print data objects. The print controller generates a second print job comprising the encrypted print data objects, the auxiliary print data objects, the unencrypted print data objects, and unencrypted print job commands, and provides the second print job.
