Abstract

PURPOSE:To enhance printing efficiency, by applying printing to printable paper supplied from a cassette during a time from the printing demand of printing data of hand insert feed paper to the beginning of printing. CONSTITUTION:A plurality of page buffers 13, 14 being cassette page buffer and hand insert page buffer for storing printing data at every cassette paper feed means and hand insert paper feed means are provided. During the storing of the printing data of the hand insert paper feed means into the hand insert page buffer from the time of the printing demand of the hand insert paper feed means to the printing start time of the printing data thereof, the printing data of a printable cassette paper feed means is printed preferentially.

Description

[Detailed description of the invention] [Industrial applicability! I+7) This invention relates to a printing device that stores print data of different feed means in a digital computer and starts printing the print data for each paper feed means in response to a print request.

[Prior art and its problems]

In conventional printing devices, paper is fed by a paper stacker, so there is no need to feed each sheet one by one, and printing is performed each time print data arrives at the printing device. In the case of paper and a plurality of cassette candy n(s), when manually feeding paper, there is a drawback that the printing operation with the cassette candy paper must be stopped from the time when manual paper feeding is requested until the start of printing.

[Purpose of the invention]

The present invention has been made in consideration of the above points, and is provided with a plurality of page buffers to store print data of manually fed paper, and prints the print data that can be fed from one paper cassette means first, thereby increasing efficiency. The purpose is to provide a printing device that prints well.

〔Example〕

FIG. 1 is a configuration diagram of an intermediate record of print data stored in a printing device.

In this figure, 1 is the rli record, 2 is the function code indicating manual paper feeding, 3 is the print data for manual paper feeding, 4 is the function code indicating cassette I-S6 paper, and 5 is cassette I-candy paper. This is the print data. In this way, intermediate record 1 is composed of function codes 2 and 4 and print data 3.5.

FIG. 2 is a schematic block diagram showing one embodiment of the present invention.

In this figure, 11d central processing unit (hereinafter referred to as CPU),
12 is a print signal bus, 13 is a page buffer for the print take 3, 14 is a page buffer for the r:IJ character data 5, 15 is a storage register indicating the content state of the page buffer 13, and 16 is a page buffer 14. 17t'' printing device, 18

Print data control will be explained below based on the print take control flowchart shown in FIG.

Note that (1) to (10) represent each step.

If both Hetufa 13 and +4 are in use, jump to step (4).

On the other hand, if either one of the page buffers 13 or 14 can be used, go to step (+), and if the next print take is print data 5, store it in the available page buffer 14 and record that it has been stored. 1,0 Stored in register 16. Here, since the print data 5 is feed paper data, the determination in step (2) is NO, and the CPU 11 starts data transfer via the paper feed signal path 21, and transfers the contents of the page buffer 14 to the print data passco 9. 8), and after outputting the contents of the page buffer 14, it is stored in the storage register 16 that the print data 5 can be stored. (After f, the CPU II checks the storage register 15.16.8) If print data 3 or 5 is stored in either page buffer 13.14, it is f, the print data of the paper feed. 3
Therefore, the process jumps to step (4), checks manual paper feed set by manual paper feed confirmation signal 20, and
starts data transfer via the paper feed signal path 21 and transfers the contents of the page buffer 13 via the print take/hess 19.

If either 3 or 14 is being stored, step (3
), and on the other hand, if both page buffers 13 and 14 can be stored, the process jumps to step (1). By executing this series of steps (1) to (10), the manual feed print data 3 is stored in the page buffer 13, and when a print request for manual feed print data is made, a cassette feeder that can continuously feed paper is used. Paper print data 5 is printed with priority.

Note that when print data requesting a paper size different from the paper size currently being printed by the printing device 17 is manually inputted to CPU+1, the print data for the paper size currently being printed is printed with priority.

〔Effect of the invention〕

According to the present invention, printing can be performed on printable cassette-fed paper between the request for printing the print data of the first feeder and the start of printing, as described in Theory 1. ,
It has the advantage of greatly improving printing efficiency.
