Printer and control method for the same

摘要

A printer in which a cover to the roll paper holder in which roll paper is held can be easily opened even when such problems as a roll paper jam occur. Opening and closing a cover (30) to the roll paper loading mechanism (2) of the printer is detected by a photointerrupter (288) detecting whether the locking lever (280) is in a locked or unlocked position. When the lock is unlocked, an cover unlocked signal is asserted to the drive control unit (39). The drive control unit (39) then drives a solenoid (62B) to switch the drive motor (61) torque transfer path from the roll paper gear train to the slip form gear train. This disengages a first gear (71) on the printer and an engaging paper.
