CLAIMS

WHAT IS CLAIMED IS:

1. A method of controlling the ejection speed of a print job, comprising: with a density module of a printing device, determining a density classifier based on a region of a plane where print fluid is to be printed for a plurality of sheets of media of a print job;

determining a percentage of each sheet of media exceeding a threshold density classifier relative to a total sheet count of the print job; and

based on the percentage, initiating an assisted ejection of the print job from the printing device.

2. The method of claim 1 , wherein the percentage to initiate the assisted ejection is 49%.

3. The method of claim 1 , wherein the density module:

determines an amount of print fluid to be placed at a first tile within the plane region achieves a density condition;

assigns a value to the plane region based on a relationship between a location of the first tile and a location of a second tile within the plane region; and

selects the density classifier based on the value of the plane region.

4. The method of claim 3, wherein the density module applies weights to the first and second tiles and wherein the weights are used to assign a value to the plane region.

5. The method of claim 1 , wherein preclusion characteristics of the print job prevents the density module from initiating.

6. The method of claim 5, wherein the preclusion characteristics include: a size of the sheet of media;

duplex printing on the sheet of media;

a humidity during the print job;

a type of print media;

a size of the print job;

or a combination thereof.

7. A printing device, comprising:

a density module to, when executed by a processor, determine:

a density classifier based on a region of a plane where print fluid is to be printed for a plurality of sheets of media of a print job; and

a percentage of each sheet of media exceeding a threshold density classifier relative to a total sheet count of the print job; and an ejection assisting module to, based on the percentage, initiate an assisted ejection of the print job from the printing device.

8. The printing device of claim 7, wherein the density module:

determines an amount of print fluid to be placed at a first tile within the plane region achieves a density condition;

assigns a value to the plane region based on a relationship between a location of the first tile and a location of a second tile within the plane region; and

selects the density classifier based on the value of the plane region.

9. The printing device of claim 8, wherein the density module applies weights to the first and second tiles and wherein the weights are used to assign a value to the plane region.

10. The printing device of claim 7, wherein the percentage to initiate the assisted ejection is 49%.

1 1. The printing device of claim 7, wherein the ejection assisting module determines which of a plurality of assisting devices to actuate based on the percentage.

12. A method of assisting an ejection of a print job from a printing device, comprising:

determining whether one of a plurality of preclusion characteristics are associated with the print job;

when the preclusion characteristics are not associated with the print job, with a density module executed by a processor:

determining a density classifier based on a region of a plane where print fluid is to be printed for a plurality of sheets of media of a print job; and

determining a percentage of each sheet of media exceeding a threshold density classifier relative to a total sheet count of the print job; and

with an ejection assisting module, initiating an assisted ejection of the print job from a printing device.

13. The method of claim 12, wherein determining a density classifier comprises, for each sheet of media:

determines an amount of print fluid to be placed at a first tile within the plane region achieves a density condition;

assigns a value to the plane region based on a relationship between a location of the first tile and a location of a second tile within the plane region; and

selects the density classifier based on the value of the plane region.

14. The method of claim 13, wherein the density module applies weights to the first and second tiles and wherein the weights are used to assign a value to the plane region.

15. The method of claim 12, wherein the percentage to initiate the assisted ejection is 49%.
