Abstract
According to an example, an apparatus may include a fluid coverage engine to determine which pixels of an image are to receive print fluid. The apparatus may also include a pixel count engine to compute a count of pixels at which print fluid is to be applied onto a media from the determined pixels of the image that are to receive print fluid, a target temperature engine to determine a target temperature for a dryer based upon the computed count of pixels, and a dryer engine to cause the dryer to become heated to the determined target temperature.
Claims19
An apparatus comprising:
- a processor;
- and
- a non-transitory storage medium storing instructions executable on the processor to:
- determine which pixels of an image are to receive print fluid;
- assign a first value to each pixel of a first subset of pixels that are to receive the print fluid;
- assign a second value to each pixel of a second subset of to pixels that are not to receive the print fluid;
- compute, based on adding the first and second values assigned to the first subset of pixels and the second subset of pixels, respectively, a count of pixels at which the print fluid is to be applied onto a media;
- determine whether the computed count exceeds a predetermined threshold count;
- in response to a determination that the computed count exceeds the predetermined threshold count, determine a target temperature to be a first target temperature for a dryer;
- and
- cause the dryer to become heated to the determined target temperature.
A method comprising:
- accessing, by a processor, print data that identifies pixels on a media where print fluid is to be deposited;
- assigning, by the processor, a first value to each pixel of a first subset of pixels that are to receive the print fluid;
- assigning, by the processor, a second value to each pixel of a second subset of pixels that are not to receive the print fluid;
- computing, by the processor based on adding the first and second values assigned to the first subset of pixels and the second subset of pixels, respectively, a count of the pixels that are to receive the print fluid;
- determining, by the processor, whether the computed count exceeds a predetermined threshold count;
- and
- in response to a determination that the computed count exceeds the predetermined threshold count, determining, by the processor, a target temperature to be a first target temperature for a dryer.
A non-transitory computer readable medium comprising instructions that when executed cause a system to:
- access print data that identifies pixels on a media where print fluid is to be deposited;
- assign a first value to each pixel of a first subset of pixels that are to receive the print fluid;
- assign a second value to each pixel of a second subset of pixels that are not to receive the print fluid;
- compute, based on adding the first and second values assigned to the first subset of pixels and the second subset of pixels, respectively, a count of the pixels that are to receive the print fluid;
- determine whether the computed count exceeds a predetermined threshold count;
- set a target temperature as a predefined lower target temperature for a dryer in response to the computed count falling below the predetermined threshold count;
- set the target temperature to a predefined higher target temperature for the dryer in response to the computed count exceeding the predetermined threshold count number;
- and
- instruct the dryer to become heated to the target temperature.
