In an example, a method comprises controlling a fluidic die to print a test pattern to a print media by moving the fluidic die sequentially in a forward and reverse direction across a width of a print media. The test pattern is printed, according to the example method, by moving the fluidic die in the forward direction and discharging printing fluid toward the print media to print a first pattern portion to the print media, advancing a print media underneath the fluidic die, and moving the fluidic die in the reverse direction and discharging printing fluid toward the print media to print a second pattern portion to the print media. The second pattern portion is shifted by a predetermined amount relative to the first pattern portion each time the fluidic die moves in the reverse direction.
