Abstract

Advertising or sales promotion information can be additionally printed on a sales receipt without changing the POS application of the POS system, which includes a terminal computer for generating first print (e.g., sales) data based on transaction information, a server for generating second print data comprising advertising or sales promotion information, and a printer in which an interface device for communication with the terminal computer and the server is installed. The interface device has a first print data processing unit and a second print data processing unit, the former of which passes the first print data received from the terminal computer to both the printer and server. The server generates the second print data based on the content of the first print data, and then sends the second print data to the interface device, which sends that data to the printer.

7. A printing system as described in claim 4, wherein the interface device interprets the first print data received from the terminal computer, temporarily stores the paper cut command when received, sends the first print data to the print processing unit without sending the paper cut command, and sends the stored paper cut command after the second print data to the print processing unit when the second print data is received from the information-providing server.

8. A printing system as described in claim 4, wherein the interface device interprets the first print data received from the terminal computer and temporarily stores at least the paper cut command without sending the paper cut command to the print processing unit when the paper cut command is received, then generates specific print data, sends the specific print data to the print processing unit, and asserts a print command.

9. A printing system as described in claim 8, wherein the interface device sends divider line print data for printing a divider line widthwise with respect to the receipt as the specific print data to the print processing unit, before asserting the print command.

10. A printing system as described in claim 9, wherein:

the terminal computer stores end marker data as last print data for printing near a trailing end of the receipt, and sends the end marker data after the first print data to the interface device;

the interface device temporarily stores the paper cut command and end marker data without sending either to the print processing unit when the paper cut command is received, and issues a divider line print data print command; and

the second print data processing unit adds the stored end marker data and paper cut command after the second print data when second print data is received, asserts a second print data and end marker data print command, and asserts a paper cut command processing instruction.

11. A printing system as described in claim 10, wherein:

if it is determined by the information-providing server that no advertising or sales promotion information is relevant to the sales information of the first print data, the information-providing server generates and sends to the interface device non-printing status data indicating that second print data has not been generated; and

the second print data processing unit of the interface device omits the second print data print command when non-printing status data is received from the information-providing server, and asserts the end marker data print command and paper cut command processing instruction.

12. A printing system as described in claim 4, wherein:
