<p>A printer with a tractor unit driven by a DC motor and a printing control method that acquires accurate load information when continuous paper is loaded. The printer has a printhead 2 that can move in a primary scanning direction and has discharge nozzles that discharge liquid onto continuous paper, and a tractor unit 4 that is driven by a DC motor Mt and conveys continuous paper toward the printhead 2 in a secondary scanning direction perpendicular to the primary scanning direction. The printer 1 and printing method also have a load information acquisition unit 23 that, when continuous paper is loaded in the tractor unit 4, drives the tractor units 4 at least two different constant conveyance speeds V1, V2, and acquires load information I1, I2 for the DC motor Mt at the at least two different conveyance speeds.</p> |
