    Abstract: In an example, a machine-readable medium stores instructions which when executed by a processor cause the processor to determine a difference between a measured printed output and an expected printed output. Based on the difference, a first control instruction for controlling a drop size wherein the drop size is variable, and a second control instruction for controlling a dot density of a variable dot density may be determined.

    Abstract: In some examples, a printing system includes a printhead comprising a nozzle array including plural columns of nozzles to deliver printing fluid to a print medium, wherein nozzles in a first column of the columns are offset from nozzles in a second column of the columns. A controller is to control printing onto the print medium using the printhead by, for each respective pass of a plurality of passes of the printhead over the print medium, controlling an advance of the print medium for a print mask pattern that controls firing of the nozzles of the printhead, where the controlled advance of the print medium causes nozzles from different columns of nozzles of the nozzle array to deliver dots of printing fluid to a given row of a swath in successive passes of the plurality of passes.
