Abstract

PURPOSE:To confirm printing data before the execution of printing by a method wherein printing data to be stored is outputted per line or page on a printing medium, such as recording paper, and the inputted printing data or the stored printing data is once displayed as an image. CONSTITUTION:When printing data to be inputted to an interface 1 is discriminated as, e.g., character data by a data processing means 6, said character data is successively displayed on a display indicating means 4 as well as first stored in a memory means 2 by a data processing. When data for one gape is all inputted, a printing is executed on the basis of a character form memory in a character generator 3. At this time, a timer means 7 is started. Therefore, at the time of inputting data for succeeding pages, the character data is repeatedly processed as mentioned above if a fixed time does not elapse from the completion of the previous display indication, and a printing is conducted when the data for the present page is all inputted. In this manner, an error printing execution is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device that prints on a page-by-page basis, that is, a bake printer.

[Prior Art 1] This type of page printer generally starts printing when one page's worth of data is input and collected. Furthermore, recently, bake printers have been known in which the printing surface is turned upside down in order to align the page order of a plurality of consecutively output recording sheets.

[Problems to be solved by the invention] However, in such conventional page printers,
When incorrect data is input due to an operator's input error, the operator does not notice the data error at least until printing is executed. *If the print side is printed upside down, the printed content is often seen for the first time after printing is completed, so if there is a data error, a lot of time is wasted, and the consumption of printing paper, toner, etc. is also large. Ta.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to display a message corresponding to the input print data on a display in advance before the input print data is outputted onto the surface of a print medium such as recording paper. This paper provides a page printer for printing.

The purpose of this is to enable print data to be confirmed in advance before printing is executed.

[Means for Solving the Problems 1] In order to achieve this object, the notebook printer of the present invention includes a print data input means into which print data is input from the outside, and a print data input means into which print data is inputted from the outside. It has a storage means for storing print data, and a printing means for outputting the print data stored in the storage means on a printing medium such as a recording paper line by line or page by page; A message display means is provided for displaying an image of the input print data or the print data stored in the storage means.

[Operation] According to the page printer of the present invention having the above configuration,
The data processing means 2 determines whether the print data received by the print data input means is, for example, graphic data representing figure information, character data representing character shapes, or 7-automatic data specifying the print position and line spacing of characters. be done. If the print data is character data, this character data is displayed on the message display means 4 and stored in the storage means 2 after undergoing data processing necessary for printing. However, since the number of characters that can be displayed at one time on the message display element Jffi 4 is limited, the timer means 7 is activated after the number of characters that can be displayed is displayed on the message display means 4, and the message is not displayed for a certain period of time. It is advisable to prevent new display from being performed on the child Pi4, because if such measures are not taken, the characters will flow on the display and become unreadable.

If the print data is graphic data, a message indicating that graphic data is being received is displayed on the message display means 4. In this case as well, after the message is displayed on the message display means 4, the timer means 7 is started, and the display on the message display means 4 is not changed for a certain period of time or more.

In addition, if the print data is 7t-matte data,
This is because the 7-o-mat data, which is merely registered in the 7-o-mat information storage section which is a part of the storage means 2 and does not require message display, is usually not very interesting data. And following the 7-ohmatsu data (
If there is other print data, the message is displayed using it.

[Example 1] Hereinafter, an example embodying the present invention will be described with reference to the drawings. As shown in FIG. 2, a switch panel 9 is provided on the front of the page printer main body 8.
Inside, in addition to various designation keys, a message display hand μ4, which is a liquid crystal display device, is provided.

FIG. 3 shows a control block diagram of the basic printer of the present invention. data processing means 6 for determining whether the data is character data, graphic data, or other 7-slate mat data, and storing character data and overlapping graphic data among the print data determined by the data processing means 6. The character shape of the character generator 3 is accessed in accordance with the instructions of the storage means 2, the character generator 3 which stores the character shape when the print data is character data, and the data processing means 6, and the character shape is accessed on a line-by-line or page-by-page basis. The apparatus is comprised of a marking means 5 for printing on a print medium such as recording paper, the message display means 4 capable of displaying characters such as letters, and a timer means 7.

As is well known in the art, the 11 classifications of print data input to the interface by the data processing means 6 are determined by the number of bytes of ASCII code contained in the print data, for example, 0 to 31 are control codes, 32 to 31 are control codes, and 32 to 31 are control codes. 12
Up to 7 is determined to be a character code, and even among control codes, up to n bytes are determined to be graphic data, and anything beyond that is determined to be 7.
This is done based on the specification of automatic data. Further, in the timer means, the flag is reset when an interrupt signal is generated when one page of character data or graphic data is displayed on the message display means 4, and the elapsed time from the time of this reset F is counted. It looks like this.

Figure 1 shows 70 steps of data processing by this page printer.
- If the data processing unit Pi6 determines that the print data input to the interface 1 indicating a chart is, for example, character data, it is first stored in the storage means 2 by data processing, and the character data is sequentially stored. It is displayed on the display display means 4. Then, when one page's worth of data is complete, printing is executed based on the character shape memory of the character generator 3. At that time, the timer means 7 is started, so when entering data from the next page onward, it is first determined whether a certain period of time has elapsed since the end of the previous display display, and if it has not yet elapsed, the character Data processing is repeated as described above, and printing is executed when the current bake data is complete.Next, when inputting print data from the next page onwards, as shown in the 70-chart, the timer means 7, it is checked whether a certain period of time or more has passed since the previous display ended. If a certain period of time has not elapsed, the character data such as the Asuto code is processed and stored in the storage means 2. On the other hand, if a certain period of time has elapsed, that character is displayed on the message display means 4.

When the number of display digits of the message display means 4 becomes full as a result of this display, the display is brought to an end state and the timer means 7 is activated.

If there is enough space in the number of display digits, the process moves directly to character data processing. Results of data processing If the data on the current page is complete, printing is executed, otherwise printing is not executed and the process returns to data input.

On the other hand, if the print data input to the interface 7 and 1 is graphic data, it is checked whether a certain amount of time has elapsed since the last display ended, and if more than a certain amount of time has elapsed, the print data is graphic data. A character string "GRAPHIC3DATA'" indicating a certain event is displayed on the message display means 4, and the display is ended, and the timer hand p'
Start i7. If a certain period of time has not elapsed, this process is not performed and the graphic data is stored in the storage means 2 without being processed. Results of data processing If the data of the current page is complete, printing is executed, otherwise, the process returns to data input without executing printing.

Note that when the print data input to the interface 7 base 1 is neither character data nor graphic data, the data is 7 mat data or control data, so the respective processing is performed. If necessary, a print operation is performed, otherwise the print operation is not performed and the process returns to data input.

[Effects of the Invention] As is clear from the details detailed above, according to the basic printer of the present invention, before starting printing, a message is displayed to the operator about the contents of the print data. Therefore, incorrect printing due to input errors or the like can be avoided.

This saves time and waste of consumables such as printing paper and toner.
