Abstract: Advertising information input control module of a POS system receives advertising information, and a billing amount calculating module calculates a billing amount based on advertising information received by input control module. A payment confirming module confirms payment of the billing amount calculated by the billing amount calculating module, and an advertising information storing control module stores the advertising information in a storing device. A check-out information input control module receives input of customer check-out information, and an advertising information retrieving module retrieves the advertising information stored in the storing device. A printing data generating module synthesizes or combines check-out information with the advertising information so as to generate printing data, which is output at a printing device, and printed as a receipt with an ad.

Abstract: A printer controller, printer control method, and data storage medium detect a real-time command pattern in the print data to prevent unintended real-time commands from being executed by the printer. The evaluating unit detects whether a command data stream for printing image data sent to a printer contains a specific data sequence. When the specific data sequence, such as the data sequence of a real-time command, is present in the command data stream, the generating unit generates a plurality of command data stream segments not containing the specific data sequence but producing printing image data identical to the image data of the original data stream to the printer; the sending unit then sends the plurality of command data stream segments generated by the generating unit to the printer.

Abstract: Printer control prevents a user from pulling on printed roll paper before the printed form is cut from the roll while still providing the printed paper quickly to the user. When a paper sensor detects the trailing end of printed portion of the paper, that portion of paper is held by an ejection roller pair to temporarily stop the end of the paper from being ejected from the ejection opening. Paper slack in the paper transportation path is then determined. A paper cutting and ejection roller driving sequence is then executed based on the slack determination to provide the printed portion of the paper to the user through the opening.

Abstract: A peripheral communications terminal and interfacing method whereby host terminal intercommunication can proceed when the communications terminal is off-line without requiring host driver interface modification. This communications terminal incorporates a communications enabling unit that selectably uses DTR signaling or similar handshaking to notify the host whether data can be received. This communications enabling unit is set to either a first "busy" mode indicating that receipt of streaming data is not possible when the processor of the communications terminal, which possesses at least a printing function, cannot further process data, or a second "override" mode which allows receipt of incoming data to continue even when the processor cannot process data.

Abstract: While eliminating the need for a dedicated on-line selector switch, a printing apparatus and control method is provided to improve the processes required to replenish consumable printing materials consumed during the printing operation. Using a transport mechanism for transporting the print medium and a printing mechanism for printing to the print medium, the printing apparatus accomplishes the printing process based on data received from a host device, selectively switches between an on-line state and an off-line state and notifies the host device of the currently selected state. The printing apparatus further comprises sensors for detecting the presence of consumable products, including roll paper and ink, that are consumed by the printing process, a switch with two functional settings, and a control device.

Abstract: An ink jet printer provided with an ink jet print head having a nozzle, an ink channel that is connected to the nozzle, and an electrostatic actuator that is composed of a diaphragm that is provided in a part of the ink channel and an electrode placed outside of the ink channel opposite to the diaphragm. The diaphragm is distorted by means of an electrostatic force generated by applying voltage to the electrostatic actuator thereby performing printing with ink droplets ejected from the nozzle. The electrostatic actuator driver comprises a timing pulse generator, charge circuit and discharge circuit. The driver controls an amount of charge to be charged to the electrostatic actuator as well as charge rate thereof corresponding to the environmental operating condition of the ink jet printer.
