Abstract: Some examples include a print system including a memory to store instructions and print data of a print job, a processor to execute the instructions in the memory to reference print data of a print job, transform the print data into a plurality of print regions of a medium representation, each of the plurality of print regions including a print density, determine the quantity of print regions having a print density exceeding a predetermined threshold, and apply a modifier to the quantity of print regions having a print density exceeding the predetermined threshold to generate a score. The print system includes a print engine to move the medium along the print path to deposit a print substance onto a medium and apply drying to the medium and a controller to control a drying of the medium along the print path of the print engine in response to the score.

Abstract: In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.
