A printer enables determining the replacement status of a printer, thereby enabling forecasting problems specific to a printer location (such as a checkout lane) and problems specific to a business, and enabling easily devising a solution to the problems. A printer 40 disposed to a printer location has an interface 48 to which memory 34 associated with the printer location (lane n) is removably connected; and a printer replacement information writer that writes printer replacement information through the interface 48 to the memory 34 at a specific time.

A method for identifying a printer and printing is provided. The method includes transmitting, from each of a plurality of printers, a wireless beacon. The method includes receiving, at a printer, an instruction from a mobile device to print information, wherein the instruction is received via a wireless network, the mobile device determining, based on radio signal strength of wireless beacons, which of the plurality of printers is closest to the mobile device and selecting and coupling to the printer via the wireless network to send the instruction to the printer. The method includes printing, at the printer selected by the mobile device, the information in accordance with the instruction.

According to an embodiment, a system for dynamically generating user interfaces for electronic receipts is disclosed. An electronic receipt management server receives and stores a first electronic receipt generated for a transaction made by a customer at a physical store, a customer identifier, and first additional information unique to the physical store. The server receives and stores a second electronic receipt for a transaction made by the customer at an online store, the customer identifier, and second additional information unique to the online store. The server transmits the first and second electronic receipts, the customer identifier, and the first and second additional information, in response to an inquiry containing the customer code. A client device displays a first graphical user interface including a first selectable object to view an image of the first electronic receipt and a second selectable object to view an image of the second electronic receipt.

According to an embodiment, a printer includes a display device and a controller device. The display device displays one of product information received from an external device and product information recorded in a memory device, as product-information-to-be-printed. When the printer is incapable of receiving the product information from the external device, the controller device controls the display device to display the product information recorded in the memory device, in a display mode indicating that the product-information-to-be-printed is the product information recorded in the memory device.
