The line printer is provided with a pinch roller for feeding a spring medium sheet by capstan drive. The pinch roller is pressed by an integrated pressing mechanism comprised of a spring holder, a pressing spring member disposed in the holder and a bearing piece connected to the spring member in contact with the pinch roller. A pressing lever is shiftable between a pressing position effective to apply pressing force to the integrated mechanism and a release position effective to release the integrated pressing mechanism. The released pressing mechanism or unit is moved away from the pinch roller to free the same to leave a significant gap between the pinch roller and a capstan roller, thereby facilitating removal of a jammed print medium sheet. Further, the integrated pressing mechanism facilitates maintenance performance of the line printer.
