A method of controlling printing by print control script embedded in a web page acquired by a client terminal from a web application server includes, after the acquired web page is displayed, accepting an input operation on the displayed web page and drawing a result of the input operation in a specific drawing area, the accepting and drawing operations being performed by the client terminal. The method further includes generating print data by converting image data written in the specific drawing area to a form enabling processing by a printer as a result of a print operation performed on the displayed web page, and commanding the printer to print the print data.

To reliably read settings information PD (network settings PD, printer settings PD) from memory and correctly set the settings information PD in a printer, a wireless tagstoring the settings information PD is disposed to a cover memberthat is removably installable to a network-connectable printing unit, a reading devicethat reads the settings information PD from the wireless tagis disposed to the printing unit, and a configuratorconfigures settings based on the read settings information PD.

A client terminal includes a web page acquisition unit that acquires from a web application server a web page embedding a print control script that operates on a web browser and controls printing related to the web page, a display unit that displays the acquired web page as a displayed web page, a drawing process unit that accepts an input operation on the displayed web page and draws a result of the input operation in a specific drawing area, a print data generation unit that generates print data by converting image data written in the drawing area to a form enabling processing by a printer according to the print control script as a result of a print operation performed on the displayed web page, and a print command unit that commands the printer to print the print data according to the print control script.

A client terminal has a web page acquisition unit that gets a web page having an embedded print control script that operates on a web browser and controls printing related to the web page from a web application server, a drawing process unit that writes input operations on the web page in a drawing area, a print data generation unit that generates print data from the image data in the drawing area according to the print control script when triggered by a print operation on the web page, and a print command unit that commands printing the print data according to the print control script.

When the printer is off-line and receives a large volume of data, the receive buffer is not filled and the communication interface with the host computer does not enter a busy state. A receive buffer temporarily stores data, including control commands, from the host computer, and the printer operates according to the sequentially interpreted content of data stored to the receive buffer. By detecting whether the printer is on-line or off-line, data in the receive buffer is cleared when the printer goes off-line and data received from the host while the printer is off-line is discarded without being buffered.

When the printer is off-line and receives a large volume of data, the receive buffer is not filled and the communication interface with the host computer does not enter a busy state. A receive buffer temporarily stores data, including control commands, from the host computer, and the printer operates according to the sequentially interpreted content of data stored to the receive buffer. By detecting whether the printer is on-line or off-line, data in the receive buffer is cleared when the printer goes off-line and data received from the host while the printer is off-line is destroyed without being buffered.

A communication terminal device autonomously activates a specific function predetermined by a host device even when the communication terminal device is off-line when the power turns on. The specific function is a function such as an offline response function or auto-status back (ASB) function for automatically reporting a status of the communication terminal device to the host device. A status monitoring command is provided. During normal operation, the host device sends this status monitoring command to the communication terminal device to store specific data in nonvolatile memory in the communication terminal device. When power turns on, the communication terminal device reads the content of this nonvolatile memory to automatically initialize the particular functions indicated by the stored content, such as an ASB or off-line response function.

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.

A line ink jet head having a plurality of ink jet head units in a staggered pattern enables the staggered ink jet head units to be easily precisely positioned to each other. The line ink jet head has ink jet head units that are staggered to each other in line with the ink nozzles disposed to the first and second head mounting surfaces on both sides of a head unit mounting layer. If the head unit mounting surface is precisely formed, the ink jet heads can be precisely positioned in staggered rows by simply bonding the ink jet head units to respective mounting surfaces.

A drive method of an ink-jet head is provided in which a diaphragm is deformed by means of electrostatic force to eject an ink droplet from a nozzle so as to prevent a residual charge from being created between a diaphragm and an individual electrode. The method has first and second drive modes. In a first drive mode a voltage of a first polarity is applied between a diaphragm of the inkjet head (common electrode) and an individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from a nozzle. In the second drive mode a voltage of a second polarity opposite to the first polarity is applied between the diaphragm and the individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from the nozzle at least once for each operation of ink droplet ejection performed in the first drive mode. According to this method, a residual charge created between the diaphragm and the electrode can be removed concurrently with performing the operation of ink droplet ejection by applying positive and negative drive voltage pulses.
