Abstract

PURPOSE:To eliminate the separation of characters and graphics between continuous two pages, by storing the data printed on the last page of a printer paper into a page buffer, and providing a switch for restoring a pointer of the page buffer to the top position due to a paper end detection signal. CONSTITUTION:A printer 6 receives printing data and a printing command from a host computer 7 through an interface 8 and stores the data for one page successively in a page buffer 9. In this state, when a printing is interrupted during the printing on the last page of a printer paper and a new printer paper is loaded and then the printing is again started, a TOF switch of an operation panel 11 is pressed down. This press-down signal allows a read buffer pointer of the page buffer 9 to travel to the top of the page buffer 9. As a result, the data printed out on the last page can be printed from the top of a predetermined page of the new printer paper, and the separation of characters and graphics between continuous two pages can be prevented from occurring.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a printer device, particularly when a printer stops in the middle of the last page of printer paper and a new printer paper is loaded, discontinuity of printing between old and new paper is prevented. The present invention relates to a printer device having a function to prevent such problems.

[Prior art]

Conventionally, in a printer device that prints on a continuous form as printer paper, when printing reaches the final page of the paper, it is common to detect the end and stop printing in the middle of the page.

In such conventional printer devices, when a new printer paper is loaded and printing is resumed, the continuation of the data printed on the last page is printed, and furthermore, the printing start position is on the page of the paper. There was a defect in that the characters and figures were separated between the new and old pages from the middle of the page, making it extremely difficult to read, making it necessary to reprint the page.

[Purpose of the invention]

The present invention has been made to eliminate the defects of conventional printer devices as described above, and when printing stops in the middle of the last page of printer paper, the data printed on that page is transferred to a new printer paper. An object of the present invention is to provide a printer device that prevents separation of characters and figures between new and old pages by printing from the top of the page.

[Summary of the invention]

In order to achieve the above object, the printer device of the present invention stores the data printed on the last page of printer paper in a page buffer, and moves the pointer of the page buffer to the beginning by a detection signal of the end of printer paper or an operator's operation. It was designed to bring it back.

[Example] The present invention will be described in detail below based on an example shown in the drawings.

Prior to explaining the embodiments, in order to facilitate understanding of the present invention, the functions of a conventional printer device will be briefly explained using FIG. 2. As shown in FIG. When the printer head 2 reaches the middle of the last page, the sensor 3 that detects the end of the current page operates and stops printing.Then, when the operator loads new printer paper 4 and resumes printing, the new printer paper 4 If printing continues from the middle of a given page, characters and graphics may be separated between the old and new pages.
[' Even if the alignment is performed at OF position 5, the characters and figures will not be separated between the old and new pages, and furthermore, the above alignment is extremely troublesome to operate.

In order to solve the above-mentioned problems, the printer device of the present invention has the following configuration.

FIG. 1 is a block diagram showing an embodiment of the printer device of the present invention, in which the printer device 6 is connected to a host combinator 7.
It receives print data and print commands from the interface 8 through the interface 8, and stores the data for one page in the page buffer 9. Reference numeral 10 denotes a system control unit which controls the drive printing unit 12 and performs printing according to the received printing commands and commands from the operation panel 11. This is to cause the printer device 61 to stop via the system control unit 10.

In the above-mentioned printer device, a dedicated TOF setting switch 14 is provided on the operation panel 11, and a push signal from this switch 14 moves the read buffer pointer of the page buffer 9 to the beginning of the page buffer.

By doing this, when printing is interrupted in the middle of the last page of printer paper and the TOF switch 14 is pressed when loading new printer paper and restarting printing, the data printed on the last page of printer paper is also updated. It is printed on paper and there is no separation of characters or graphics between old and new pages.

However, as mentioned above, if the TOF switch 14 is simply provided with the function of returning the page buffer 90 buffer pointer to the beginning, printing will start on the new page from the line next to the line that has already been printed on the previous page. When printing a blank diagram, it is inconvenient that the diagram may extend beyond the page.

In order to solve this problem, as shown in FIG. 3, a function for returning the count value of the line counter 15 originally owned by the printer device 6 to zero may be added to the TOF setting switch 14.

By doing this, when the TOF setting switch 14 is pressed when a new printer paper is loaded, the printer head 2 will start printing from the TOF position 5 of a predetermined page of printer paper. Not only does the separation of figures not occur, but also data for one member can be contained within a desired page.

The functions of the printer device of the present invention described above are shown in a flowchart as shown in FIG.

In the above, only the case where the TOF setting switch is used to move the page buffer pointer and clear the line counter has been described.2 The present invention does not need to be limited to this. It may be possible to move the page buffer and clear the line counter, or it may be possible to select between manual and automatic movement.

〔Effect of the invention〕

Since the present invention is configured and functions as explained above, it is only necessary to slightly change the software built into the printer device and add a dedicated TOF setting switch if necessary, when newly loading printer paper. Not only can it prevent the separation of characters and figures between old and new pages, but also
Since a page's worth of data can always be accommodated within a desired page, there is no need to print or reprint, and this is extremely effective in giving a sense of security to inexperienced operators and making operations easier.
