Abstract

Disclosed herein is a method of operating a printing system including determining a time of a print problem, accessing a database containing a timeline of print-related attribute changes, modifying one or more print-related attributes, and resubmitting print jobs. In another embodiment, a method of operating a printing system involves storing sets of print-related attributes in a settings repository, the stored sets being available for use in processing future print jobs. Corresponding printing systems also are disclosed. The methods and systems can be used to improve the efficiency and/or quality of high volume printing operations.

Claims

1. A method of operating a printing system, comprising:

forming a database containing a timeline of print-related attribute changes,

determining a time of a print problem,

accessing a database containing a timeline of print-related attribute changes,

reviewing a portion of the timeline of print related attribute changes proximate the determined time of the print problem,

modifying at least one print-related attribute in effect proximate the time of the print problem, and

after modifying, resubmitting print jobs.

2. The method of claim 1, wherein the timeline includes changes in at least one of print output attributes, pre-press attributes, and printer set-up attributes.

3. The method of claim 1, wherein the at least one print-related attribute includes a system level attribute.

4. The method of claim 1, wherein the at least one print-related attribute includes a queue level attribute.

5. The method of claim 1, wherein the at least one print-related attribute includes at least one system level attribute and at least one queue level attribute.

6. The method of claim 5, wherein the modified print-related attributes are saved as part of a set of print-related attributes in a settings repository for future use.

7. The method of claim 5, wherein the timeline is stored in a memory of a computer at least indirectly operative of printing hardware.

8. The method of claim 5, further comprising capturing sets of print-related attributes and storing the sets in a settings repository for future use.

9. The method of claim 1, wherein the timeline is stored in a memory contained in a computer at least indirectly operative of printer hardware.

10. The method of claim 1, further comprising continuously revising the timeline of print-related attribute changes during printer operation and storing changes in a memory.

11. The method of claim 10, wherein the timeline includes changes in at least one of print output attributes, pre-press attributes, and printer set-up attributes.

12. The method of claim 1, wherein modifying comprises reinstating a prior print-related attribute affecting image quality.

13. The method of claim 1, wherein modifying at least one print-related attribute comprises modifying a print-related attribute that was changed proximate the determined time of the print problem.

14. The method of claim 13, further comprising capturing sets of print-related attributes and storing the sets in a settings repository.

15. The method of claim 14, wherein the sets of print-related attributes include both system level attributes and queue level attributes.

16. The method of claim 1, wherein modifying at least one print-related attribute comprises changing printing conditions without revising print-related attributes.

17. A method comprising forming a settings repository of print-related attribute sets, at least one set including job level attributes, at least one system level attribute selected from the group consisting of font, security level, caching and tone reproduction curve, and at least one queue level attribute selected from the group consisting of color, caching and priority, selecting a print-related attribute set from the settings repository, and submitting at least one print job with the selected print-related attribute set.
