## Abstract

Systems and methods are provided for reviewing printed jobs. One embodiment is a system that includes a print review device. The print review device includes a memory that stores data which indicates whether regions along a width of print media marked by a printer are flagged as bypassable, and a controller configured to determine printhead conditions along the width of the print media, associate each printhead condition with a corresponding region, and to generate a report with notifications of printhead conditions within each region that has not been flagged, while suppressing notifications of printhead conditions within regions that have been flagged.

## Claims

### Claim 1

A system comprising:
a print review device comprising:
a memory that stores data which indicates whether regions along a width of print media marked by a printer are flagged as bypassable; and
a controller configured to determine printhead conditions along the width of the print media, associate each printhead condition with a corresponding region, and to generate a report with notifications of printhead conditions within each region that has not been flagged, while suppressing notifications of printhead conditions within regions that have been flagged.

### Claim 2 (depends on 1)

The system of claim 1 wherein:
the print review device further comprises an image capture device configured to iteratively capture images in real-time as the printer prints; and
the controller is configured to generate reports in real-time as the printer prints.

### Claim 3 (depends on 1)

The system of claim 1 wherein:
the controller is configured to generate reports for a printer that prints each of multiple color planes.

### Claim 4 (depends on 1)

The system of claim 1 wherein:
regions that are flagged as bypassable cause the printer to forego global error handling settings for the printer in that region.

### Claim 5 (depends on 1)

The system of claim 1 wherein:
the controller generates a user interface configured to indicate each region as a two dimensional area on an image of the test pattern.

### Claim 6 (depends on 1)

The system of claim 1 wherein:
printhead conditions are associated by the controller with locations having a width of at least ten nozzles at a printhead of the printer.

### Claim 7 (depends on 1)

The system of claim 1 wherein:
each of the printhead conditions is associated with a region based on a mapping of a location of that printhead condition to a region.

### Claim 8 (depends on 1)

The system of claim 1 further comprising:
the printer, the printer being configured to mark the print media.

### Claim 9

A method comprising:
storing data which indicates whether regions along a width of print media marked by a printer are flagged as bypassable;
determining printhead conditions along the width of the print media;
associating each printhead condition with a corresponding region; and
generating a report with notifications of printhead conditions within each region that has not been flagged, while suppressing notifications of printhead conditions within regions that have been flagged.

### Claim 10 (depends on 9)

The method of claim 9 further comprising:
iteratively capturing images of the print media in real-time as the printer prints, wherein
generate the report is performed in real-time as the printer prints.

### Claim 11 (depends on 9)

The method of claim 9 further comprising:
generating reports for a printer that prints each of multiple color planes.

### Claim 12 (depends on 9)

The method of claim 9 wherein:
foregoing global error handling settings at a printer that marks the print media in regions that have been flagged.

### Claim 13 (depends on 9)

The method of claim 9 wherein:
the controller generates a user interface configured to indicate each region as a two dimensional area on an image of the test pattern.

### Claim 14 (depends on 9)

The method of claim 9 further comprising:
associating printhead conditions locations having a width of at least ten nozzles at a printhead of the printer.

### Claim 15 (depends on 9)

The method of claim 9 further comprising:
marking the print media via the printer.

### Claim 16

A non-transitory computer readable medium embodying programmed instructions which, when executed by a processor, are operable for performing a method comprising:
storing data which indicates whether regions along a width of print media marked by a printer are flagged as bypassable;
determining printhead conditions along the width of the print media;
associating each printhead condition with a corresponding region; and
generating a report with notifications of printhead conditions within each region that has not been flagged, while suppressing notifications of printhead conditions within regions that have been flagged.

### Claim 17 (depends on 16)

The medium of claim 16 wherein the method further comprises:
iteratively capturing images of the print media in real-time as the printer prints, wherein
generate the report is performed in real-time as the printer prints.

### Claim 18 (depends on 16)

The medium of claim 16 wherein the method further comprises:
generating reports for a printer that prints each of multiple color planes.

### Claim 19 (depends on 16)

The medium of claim 16 wherein:
foregoing global error handling settings at a printer that marks the print media in regions that have been flagged.

### Claim 20 (depends on 16)

The medium of claim 16 wherein:
each of the printhead conditions is associated with a region based on a mapping of a location of that printhead condition to a region.
