Printing apparatus and printing method

A printing method of a printing apparatus,

• the printing apparatus including:
• a controller;
• a printing unit including a printing head;
• and
• a front driving roller and a nip roller disposed upstream of the printing unit and configured to nip and transport the substrate, and
• the printing apparatus being configured to transport the substrate in a roll-to-roll scheme, wherein
• the controller controls the printing unit such that a transport of the substrate is started from a state where the transport of the substrate is stopped and printing is started after a transport distance of the substrate reaches a pre-discharge transport distance, and wherein
• the printing method comprises a first pre-discharge transport distance setting step for setting the pre-discharge transport distance to a value not less than a first longest distance, provided that a transport distance in a condition, in which the transport distance is a longest distance, among Conditions 1, 2, and 3 provided below is the first longest distance, wherein
• Condition 1 is a transport distance until a region of the substrate that was nipped between the front driving roller and the nip roller passes through the printing head disposed most downstream in a transport path of the substrate,
• Condition 2 is a transport distance until a transport speed of the substrate becomes constant, and
• Condition 3 is a transport distance until tension of the substrate being transported becomes stable.
