Abstract
A method of detecting droplets of printing fluid output from a nozzle array includes, in an example, grouping a number of nozzles into a number of individual groups of nozzles and sequentially detecting, with a printing fluid detector, printing fluid ejected from each group of nozzles using a linear position encoder to synchronize the position of the printing fluid detector wherein the printing fluid detector stops moving while detecting each group of nozzles.
