1. A recording apparatus comprising:
a liquid ejection head having nozzles and a nozzle surface to which the nozzles are formed;
a controller;
a signal input part through which a user inputs, to the controller, a setting signal indicating settings related to a grade of a barcode or two-dimensional code; and
a gap changing unit configured to change a gap between the nozzle surface and a recording medium by relatively displacing the liquid ejection head and a recording medium in a direction intersecting with the nozzle surface,
wherein the controller drives the liquid ejection head based on the setting signal input through the signal input part to cause the nozzles to eject liquid to record a barcode or two-dimensional code on the recording medium in the grade corresponding to the setting signal,
wherein the recording apparatus includes a relative displacement unit configured to cause the liquid ejection head and the recording medium to relatively displace in a direction parallel to the nozzle surface, and
wherein the controller:
performs the setting including a setting related to an ejection speed of liquid from the nozzles based on the setting signal input through the signal input part;
controls the relative displacement unit to cause the liquid ejection head and the recording medium to relatively displace and, at the same time, drives the liquid ejection head based on the setting to eject liquid from the nozzles to record a barcode or two-dimensional code on the recording medium;
makes a relative displacement speed between the liquid ejection head and the recording medium by the relative displacement unit faster as the liquid ejection speed corresponding to the setting signal gets faster; and
controls the gap changing unit to select a size of a platen gap between the nozzle surface and the recording medium based on the relative displacement speed, including making the platen gap size greater as the relative displacement speed between the liquid ejection head and the recording medium by the relative displacement unit gets faster.
