Commodity-data processing apparatus

A commodity-data processing apparatus comprising:

• a housing having a printer housing space;
• a printer unit mounted in the housing and movable between a housed position at which the printer unit fits in the printer housing space and a drawn-out position at which the printer unit is drawn out of the printer housing space, the printer unit including a cover that is movable between a closed position and an open position when the printer unit is at the drawn-out position and not movable between the closed position and the open position when the printer unit is at the housed position;
• a printer sensor configured to detect a position of the printer unit;
• a cover sensor configured to detect a position of the cover of the printer unit;
• an anomaly sensor configured to detect an anomaly of the printer unit;
• and
• a controller configured to:
• determine whether the printer unit is moved from the housed position to the drawn-out position based on the detected position of the printer sensor,
• determine whether the cover is moved from the open position to the closed position based on the detected position of the cover sensor, when determining that the printer unit is moved from the housed position to the drawn-out position,
• determine whether or not there is an anomaly in the printer unit based on a detection result of the anomaly sensor, upon determining that the cover is moved from the open position to the closed position, and
• enable receipt printing of a limited number by the printing unit, upon determining that there is no anomaly in the printer unit.

A method for controlling a commodity-data processing apparatus including a housing having a printer housing space and a printer unit mounted in the housing and movable between a housed position at which the printer unit fits in the printer housing space and a drawn-out position at which the printer unit is drawn out of the printer housing space, the printer unit including a cover that is movable between a closed position and an open position when the printer unit is at the drawn-out position and not movable between the closed position and the open position when the printer unit is at the housed position, the method comprising:

• determining whether the printer unit is moved from the housed position to the drawn-out position
• determining whether the cover is moved from the open position to the closed position, when determining that the printer unit is moved from the housed position to the drawn-out position;
• determining whether or not the printer unit is ready for printing, upon determining that the cover is moved from the open position to the closed position;
• and
• enabling receipt printing of a limited number by the printing unit, upon determining that the printer unit is ready for printing.
