Abstract

A printing medium transport apparatus and method and printing apparatus which is capable of properly transporting a printing medium by the cooperation of two rollers under independent drive without incurring the complication, size increase and price increase of the apparatus. In the course of transporting a sheet by the cooperation of feed and transport rollers, deceleration/stop control is made on feed and transport motors to be respectively driven such that the rollers are simultaneously stopped from rotating. When the transport roller stops from rotating that is located downstream side on a transport path of a printing medium in case the feed roller is rotating that is located upstream side on the transport path, the feed motor driving the feed roller is forcibly stopped.
