Abstract
An inkjet printing apparatus is provided which can print images with no print quality variations. For this purpose, the fluid viscosity resistances between the print head and the print medium beneath respective nozzle arrays that occur as the print head moves in the forward direction are made equal to those that occur as the print head moves in the backward direction.
