Abstract

PURPOSE:To make it possible to instantaneously judge whether the new page after the resetting of paper is the beginning of a manuscript, by printing a printed matter discarding message when the absence of paper is detected and printing the content stored in an output buffer part from the beginning after the resetting of the paper. CONSTITUTION:When the absence of paper is detected by a paper absence detection part 9, a data analytical part 2 reads the printed matter discarding message of a prepared data table 6 from a character generator 7 by the output signal of said detection part 9 and inserts the same in the head of an output buffer part 3 to drive an output control part 4 to perform printing. The output buffer part 3 stores the content thereof without erasing the same until a page is finished to deliver data to the output control part 4 and, therefore, even if the absence of paper is detected on the way of the page, printing can be again performed from the beginning of the page when the paper is reset. The output buffer part 3 is a register shiftable to both left and right directions.

Description

[Detailed Description of the Invention] [Summary] In a page-type printer that has a printing speed that is slower than the data reception speed and the length of one page is undefined, the printing of the received data is not completed. If there is no paper, etc., the received data is printed starting from the end of the page after setting the paper.

[Industrial application field]

The present invention relates to a device that monitors input manuscripts, which is widely used in newspaper companies, etc., and particularly when the length of the page is undefined and the page cut is cut, data from the host computer is monitored. This relates to an additional printer printing method in which when the speed of the output device is slow relative to the transfer and the paper runs out while outputting the received data, a message is output in the middle of printing, and printing is performed from the end of the page by resetting the paper. .

Conventional apparatuses have a drawback in that when the paper runs out during the output of received data, the breaks in the text are unclear, and an improvement in this problem has been strongly desired.

[Conventional technology]

In conventional devices for monitoring input manuscripts at newspaper companies, etc., if the paper runs out during printing, the paper is reset and printing starts from the next character.

FIG. 2 is a diagram illustrating a conventional printing situation.

In other words, conventional print control receives data such as character codes and order codes from a host computer and stores it in a reception buffer, outputting it vertically or horizontally in the order in which it was stored, character pitch, line pitch, etc. The output is controlled while calculating the number of characters in a line, etc. In this case, it often happens that the printer runs out of paper during output.

In a case like this, even if the host computer is notified that the paper is out after detecting that it is out of paper, the host computer
Since the host computer has already sent the data, it does not know where to start again.

Therefore, the conventional printing format was usually to print as shown in FIG.

That is, the first page, second page, and third page are printed in sequence according to the entire manuscript, and on the fourth page, "Aiueo, kakikukeko, sasisususeso, . . ." is printed.

In this case, it is assumed that the printer paper runs out at the 4th page, at the point where it reads, ``Aiueo, kakikukeko,''.

In this case, according to the conventional method, after the paper is reset, printing of "Sashisu Seso" is started from the beginning of the new page (indicated by the dotted line).

[Problem that the invention seeks to solve]

Therefore, when printer paper runs out, you can check whether the original has ended at the fourth page, whether there is a continuation, and whether the new page (indicated by the dotted line) after resetting the paper is the beginning of the original. I can't make a decision right away, I have to read the contents of the 4th and 5th pages before making a decision. This had the disadvantage of being inappropriate for a job like a newspaper company, where every minute counts.

The purpose of the present invention is to print "[Printing in progress]" at the end of the old paper as shown in Figure 3, and then print "Aiueo, kakikukeko" on the new page (indicated by the dotted line) on the fourth page after resetting the paper.
The purpose of this is to print ``Sashisu Seso...'' so that it can be immediately determined whether or not the new page after resetting the paper is the first page of the manuscript.

[Means for solving problems]

As shown in FIG. 1, when the paper out detection section 9 detects a paper out state, the data analysis section 2 generates a printed material disposal message [in the middle of printing] in the data table 6 prepared in advance based on its output signal. The output buffer section 3 stores the contents without erasing them until the end of the page, and then inserts the contents into the beginning of the output buffer section 3 and drives the output control section 4 to print. After resetting, the data is passed to the output control section 4 and printed.

[Effect]

According to the present invention, when a printout is detected, a printed material disposal message [in the middle of printing] is printed, and after paper re-safety), the contents stored in the output buffer section 3 are printed from the beginning. Therefore, it is only necessary to unconditionally discard a document on which the waste message [printing in progress] is printed, and it is easy to immediately determine whether a new page is the beginning of the document or not, and it is possible to prevent double output of the output document. This effect is produced.

〔Example〕

FIG. 1 is a diagram showing an embodiment of a printer additional printing method according to the present invention.

In the figure, 1 is a reception buffer, 2 is a data analysis section, 3 is an output buffer section, 4 is an output control section, 5 is a timing generation section,
6 is a data table, 7 is a character generator, 8 is a printing section, 9
is the paper out detection section.

The present invention will be described in detail below with reference to the drawings.

The reception buffer 1 is a buffer that receives and stores data sent from the host computer. When the buffer is full, input is prohibited and the data is passed to the data analysis section 2.

The output buffer unit 3 outputs character patterns from the character generator 7 to the analyzed data, and develops the data into an image to be output.

The output control section 4 is a control section that outputs the contents of the output buffer section 3 while monitoring the state and speed of the printing section 8.

The timing generator 5 is a part that generates timing for controlling the reception of data in the reception buffer 1, the readout of the data table 6, the readout of the character generator 7, and the like.

The printing unit 8 is a printer that actually prints, and the paper out detection unit 9 is a part that detects paper out.

The data table 6 is composed of a ROM, and stores, for example, control codes, character code ranges, and the like. The character generator 7 is also composed of a ROM, and stores character patterns.

The data sent from the host computer is input to the reception buffer l based on the signal from the timing generator 5.

The data stored in the data table 6 prepared in advance and the contents of the reception buffer 1 are manually analyzed by the data analysis unit 2, and the control codes (character pitch, line pitch, /ch,
If it is a character code, the character pattern is read out from the character generator 7 prepared in advance and stored in the output buffer part 3.

The output control section 4 reads out the stored contents of the output buffer section 3 in accordance with the printing speed of the printer, and controls the printing section 8 to perform printing.

At this time, when paperless detection section 9 detects paperless paper, data analysis section 2 uses the output signal from paperless detection section 9 to generate printed material disposal message [
[in the middle of printing] is read out from the character generator 7, inserted at the beginning of the output buffer section 3, and the output control section 4 is driven to print.

The output buffer section 3 stores the contents without erasing them until the end of the page, and passes the data to the output control section 4. Therefore, even if a blank is detected in the middle of a page, the paper will not run out. When the page is re-cented, it is possible to print again from the beginning of the page as shown in FIG. Note that the output buffer unit 3 is a register that can be shifted in both left and right directions.

In addition, in the above explanation, for example, [
] was used, but it does not necessarily have to be this character.

〔Effect of the invention〕

As explained in detail above, the present invention has the great effect of eliminating double cuts that occur due to duplication of cutting tools in businesses that require speed and accuracy, such as newspaper companies, and providing an accurate and easy-to-use device. There is.
