摘要： A printing apparatus of the present invention includes a print head having a plurality of nozzles, from which ink droplets are ejected, a light detection unit that has a light emitting element and a light receiving element and determines the active or inactive state of the nozzles based on whether or not the light beam is intercepted by ink droplets, and a carriage that moves the print head relative to the light detection unit. The light beam emitted from the light emitting element has an optical axis that is inclined at a predetermined angle to a nozzle array. At least part of the plurality of nozzles are inspected while the print head is moving relative to the light detection unit at a fixed speed.

摘要： A printer, a printer control method and control program, a POS terminal device, and a cash drawer drive device detect when a non-standard cash drawer is connected, and prevents a non-recoverable overcurrent protection device from operating (such as a fuse blowing) by preventing an overcurrent from flowing to the cash drawer. A printer 10 that can be connected to and drive a cash drawer 20 has a cash drawer drive circuit unit 12 that supplies drive current for driving a lock release coil 21 to open/close the cash drawer 20, a coil resistance detection unit 14 that detects the resistance of the lock release coil 21, and a drive switching unit 15 that connects the cash drawer drive circuit unit 12 or connects the coil resistance detection unit 14 to the lock release coil 21.
