Title
(EN) APPLY THERMAL ENERGY TO SUB-LINES
Abstract
(EN)

Example implementations applying thermal energy to sub-lines. In some examples, a printing device can include a processing resource and a memory resource storing non-transitory machine-readable instructions to cause the processing resource to receive print data about a line to be formed on a thermally activated print medium, divide the line into a plurality of sub-lines, determine a threshold colorant density level of a first sub-line and a third sub-line of the plurality of sub-lines based on the received print data, and cause a print head of the printing device to apply thermal energy to the first sub-line and the third sub-line on the thermally activated print medium using the received print data.
