Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer for performing printing in accordance with data input from a host computer. 2. Description of the Related Art Conventionally, data input from a host computer is in accordance with a printer control language specific to data interpreting means, and the data includes a character code and a discharge command. I have. [0003] The printer device has data interpreting means, which interprets the input data and prints the meaning of the data. A control panel comprising various buttons and a display panel is provided on the upper surface of the printer so that online control of data input and various settings such as the number of copies can be performed. . [0005] Since there are many known data interpreting means for which this technique has already been put to practical use, a detailed description thereof will be omitted. However, there is a case where data sent from the host computer is not printed as desired due to a mistake in selection of the data interpreting means. [0007] In this case, there is a problem that a large amount of erroneously printed paper appears in some cases, which is very annoying to the user and uneconomical. On the other hand, many conventional printers can be put into an off-line state by pressing an online button on a control panel to stop data input. In many cases, more data than the data being developed by the data interpretation means is already captured in the printer, and as a result, useless printing is often not stopped even when the printer is offline. There was a problem. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem. When a printed result is not desirable for a user, printing can be immediately interrupted, and subsequent printing is not performed. It is an object of the present invention to provide a printer device that can perform the above operations. In order to achieve this object, a printer according to a first aspect of the present invention includes a data interpreter for interpreting data in accordance with data in a printer control language, and a printer. And a control panel that enables various settings of the printer, and prints in accordance with data transmitted from the host computer. The printer is operably provided on the control panel so that print data is not used during printing. A data ignoring operation body operated to cause the data interpreting means to be used as print data based on the operation of the data ignoring operation body, and If you do not use the data as the print data by ignoring means, termination de <br/> of the printer control language Interpret the data Then, to cancel the effect of the data ignored means
It is characterized by being configured to terminate the unused state Te. According to the first aspect of the present invention having the above-mentioned configuration, as shown in FIG. 1, data transmitted from a host computer is provided. If the printing desired by the user is not performed due to a mistake in the selection of the data interpretation means or the like when performing printing in accordance with the above, the data ignore operation body on the control panel is operated. Based on the operation of the data ignoring operation body, the data ignoring means prevents the input data from being used as print data while the data interpreting means interprets the data of the printer control language. And
The data is regarded as print data by the data ignoring means.
The printer control language

Is released to end the unused state. An embodiment in which the present invention is embodied in a laser printer will be described below with reference to the drawings. FIG. 2 is a block diagram showing a control circuit of the laser printer of this embodiment. The microcomputer section 20, which is the main part of the control circuit, includes a CPU 3, a program ROM 4, a dot data memory 5, a working memory 6,
And a text memory 7. The CPU 3 and the like are connected by a bus 10, and the input unit 1 and the printing unit 2 are connected to the bus 10. The input unit 1 inputs necessary data to the microcomputer unit 20, and the printing unit 2 converts the dot data stored in the dot data memory 5 based on a command from the microcomputer unit 20. This is a part performed by the electrophotographic method. The program ROM 4 stores a program for data interpretation means for creating dot data. The dot data memory 5 is for storing dot data generated from input data. The working memory 6 is for temporarily storing data required when the CPU 3 executes a program. The text memory 7 is for storing data such as a character code and a character size input from the input unit 1. FIG. 3 is a diagram showing a control panel 30 installed on the upper side surface of the laser printer according to the present embodiment. The control panel 30 includes an online button 31 for enabling online / offline control, a menu button 32 for performing an instruction operation for displaying various menu contents, a setting button 33 for setting the menu, and an input unit. 1, a data ignore button 34 for setting a data ignore flag to the data interpreting means to notify the data interpreting means so as not to use the data inputted from 1 as print data, a display panel 35 for displaying a menu or the like; Data lamp 36 indicating whether data exists in the
And is constituted by. The data ignore button 34
Constitutes the data ignoring operation body of the present invention. A method of creating print data in accordance with data input from the host computer will be described below with reference to FIGS. As shown in FIG. 4, first, if it is in the online state in step S1, the data for printing sent from the host computer is inputted from the input unit 1 in step S2, and stored in the text memory 7 in step S3. I do. The operations from step S1 to step S3 operate independently of the data interpreting means. As shown in FIG. 7, when the data ignore button 34 on the control panel 30 is pressed during off-line in step P1, a data ignore flag is set in step P2, and the data interpreting means is set in step P3. Is initialized. The process of step P3 functions as the initialization means of the present invention. Further, thereafter, in step P4, the online state is established, and the data is again taken in from the input unit 1. The pressing of the button on the control panel 30 is performed in the CPU 3 by an interrupt process, and the process of setting the data neglect flag is performed during the interrupt. As shown in FIG. 5, as the operation of the CPU 3, if it is confirmed in step T1 that data is stored in the text memory 7, the operation proceeds to step T1.
In 2, the data interpreter inputs the data stored in the text memory 7. Next, in step T3, it is determined whether or not a data ignore flag that is set by pressing the data ignore button 34 on the control panel 30 is set. If the data ignore flag is not set. In this case, a command analysis is performed in step T4, and an operation according to the input data is performed in step T5. Specifically, when the character code is sent, a bitmap of the character of the character code is created and stored in the dot data memory 5. After setting the dot data, the dot data stored in the dot data memory 5 is used by the printing unit 2 for printing. If it is confirmed in step T3 that the data ignore flag has been set, then in step T6
So that the data is not used as print data as a data interpretation means program. Step T6
The processing step functions as the data ignoring means of the present invention. Then, in step T7, it is checked whether or not the input data is the job end data in the printer control language.
In step 8, the data ignore flag is cleared. Here, when the data ignore flag is cleared, the subsequent data is used for normal printing. The processing in step T7 functions as the job end data detecting means of the present invention. Also, As shown in FIG. 6, when it is confirmed at step R1 that data is stored in the text memory 7, the data lamp 36 is turned on and off at step R2. This operation is performed in the CPU 3 by processing within a timer interrupt. The following is a description of the processing of the present invention when the printed result is not what the user desires, which is the gist of the present invention. When printing is performed in accordance with the above procedure in accordance with the printing data sent from the host computer,
After printing the first sheet, the user checks the printing result, and presses the online button 31 on the control panel 30 when the printing is different from the printing desired by the user. As a result, the data sent from the host computer is temporarily stopped. In this case, the data interpretation means is already in the text memory 7
Is sequentially interpreted and printing is continued. Next, the user presses the data ignore button 34 on the control panel 30. As a result, the interface which has been in the off-line state changes to the on-line state, and the data sent from the host computer is sequentially stored in the text memory 7 again. At this time, data remains in the dot data memory 5 and the data lamp 36 is lit, but when the data ignore button is pressed,
The data interpreter is initialized and ready for the next data input. Until job end data in the printer control language indicating the end of a series of data is input, processing for not using the data as print data is performed when data is taken in from the text memory 7. When job end data is sent from the host computer, the data interpreting means again interprets the data fetched from the text memory 7 as usual. In this embodiment, the period during which the input data is not used as print data is set to the time until job end data indicating the end of data specific to the printer control language is input. It may be limited while the user keeps pressing the ignore button. In this case, the period during which the data is not used as print data can be arbitrarily determined based on the user's free will. In addition, after the data neglect button is pressed, a configuration may be adopted in which a data end detection unit that detects that a series of data that is continuously input is no longer input and ends the data neglect state is provided. Good. In this embodiment, the control panel is composed of four buttons, a display panel, and a data lamp. However, if there is a data ignoring operation body which is the gist of the present invention, any control panel can be used. It may be configured. The present invention can be applied to a printer other than a laser printer for printing figures. In addition, the present invention can be implemented in various modified and improved forms based on the knowledge of those skilled in the art. As is apparent from the above description,
ADVANTAGE OF THE INVENTION According to the printer apparatus of this invention, when the result printed in the middle of printing is not interesting to a user, if a data neglect operation body is operated, printing can be interrupted immediately and the subsequent useless printing can be reliably performed. Can be stopped.
Then, the data is printed by the data ignoring means.
If not used as data, the printer
When interpreting the end data of the control language,
Releasing the action of the step to end the unused state.
it can.
