ABSTRACT:
A sheet bundle printer peeling off and performing printing on an uppermost sheet of a peelably adhered sheet bundle includes a print head performing printing on the sheet, a platen roller, at a print position, cooperating with the print head to feed both the sheet and an ink ribbon, pinched therebetween, and a platen moving mechanism moving the platen roller between the print position and a non-print position. The platen moving mechanism includes a manual operation device manually moving the platen roller from the print to non-print positions and a press roller that made to contact or moved away from the platen roller by the manual operation device to move the platen roller from the print to non-print positions while pressing it when the press roller contacts it. At the non-print position, the sheet is allowed to pass between the press roller and the platen roller.
