Abstract

PURPOSE:To make printing data for desired number of copies formed of printing data that are supplied from a host computer by only one-time of transmission by a method wherein information regarding the number of copies for printing transmitted from the host computer is stored in a job modification information memory. CONSTITUTION:Data received from a host computer 11 and stored in a disk 13 are read out through a disk control section 14, and editing processing is applied thereto for converting the same into printing data developed in bit patterns. In this processing of editing, the number of duplications 21c are found to be S times by detection with job modification information 21 in a format, and the number of duplications in S times are stored by operation of a maim control section 12 in a job modification information memory 20. After reading out of the data is made and editing processing is applied to the data based on the information stored in the job modification information memory 20, the data in a number of pages are printed S times.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing device used as an output device of an information processing device.

0002

[Background Art] When printing multiple copies of print data consisting of multiple pages, a conventional printing device used as an output device of an information processing device transmits the print data from a host computer the same number of times as the number of copies to be printed. is configured to print.

0003

[Problems to be Solved by the Invention] As described above, conventional printing apparatuses are configured to send print data for multiple pages from a host computer multiple times equal to the number of copies to be printed. This method has the drawback that the creation of the next print data is delayed and the print data creation efficiency is reduced.

[Means for Solving the Problems] A printing apparatus of the present invention includes a disk device for storing data sent from a host computer, a disk control section for controlling the operation of the disk device, and a disk device for storing data sent from a host computer. A page buffer memory that temporarily stores characters for high-speed processing, and a character pattern memory that stores character dot patterns.
a drawing control unit that develops print data for each page stored in the page buffer memory into a bit pattern of a bit string corresponding to one side of printing paper by reading a corresponding character pattern from the character pattern memory;
A drawing memory that stores bit patterns for one side of printing paper developed by the drawing control unit and m-byte print data transmitted along with the print data are set as one job, and the job is copied. a job modification information memory that stores data instructing the number of times to print, a printer unit that prints the bit pattern print data read from the drawing memory by the drawing control unit onto printing paper, the disk control unit and the page buffer memory. and a main control section that controls operations of the character pattern memory, the drawing control section, the drawing memory, the job modification information memory, and the printer section.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is a format diagram showing an example of job execution information in the embodiment of FIG. 1, and FIG. 3 is a diagram of a job modification information memory in the embodiment of FIG. A format diagram showing an example of a recording format, and FIG. 4 is a flowchart showing the operation of the embodiment of FIG.

In FIG. 1, 11 is a host computer. Reference numeral 12 denotes a main control unit that receives print data sent from the host computer, develops it into a bit pattern, and controls a series of printing operations. 13
is a disk device that can store a large amount of data. 14 writes print data received from the host computer 11 to the disk device 13 according to a write instruction from the main control section 12, and when developing the print data into a bit pattern, reads it from the disk device 13 according to a read instruction from the main control section 12. This is a disk control unit that performs 20 stores data instructing the number of times to copy a job when m-byte print data transmitted along with the print data from the host computer 11 is set as one job, according to an instruction from the main control unit 12. This is job qualification information memory. Reference numeral 15 denotes a page buffer used as a cache memory capable of storing print data to be developed into dot patterns for each page at high speed according to instructions from the main control unit 12, and reading the data at high speed for printing. It's memory. Reference numeral 16 denotes a character pattern memory that stores dot patterns of characters. 17 corresponds to one side of printing paper by reading the corresponding character pattern from the character pattern memory 16 from the print data for each page stored in the page buffer memory 15 according to the command from the main control unit 12. This is a drawing control unit that develops a bit string into a bit pattern. Reference numeral 18 denotes a drawing memory that stores the bit pattern for one page of printing paper developed by the drawing control unit 17. The drawing control section 17 also reads out bit pattern print data stored in the drawing memory 18 in response to a command from the main control section 12 . 19 is a drawing control unit 17 according to a command from the main control unit 12.
is a printer unit that prints the bit pattern print data read from the drawing memory 18 onto printing paper.

The printing apparatus configured as described above reads data received from the host computer 11 and stored in the disk device 13 via the disk control unit 14, and performs an editing process to convert the data into print data developed into a bit pattern. However, at this time, the main control unit 12 detects that the number of copies 21c is S times based on the job modification information 21 in the format shown in FIG.
The following job capacity 21b (m = N x a bytes), the job capacity counter as count data for editing this job capacity, the number of copies S, and the starting position of the print data to be copied. The memory address (job start address) of the disk device 13 shown in FIG.
Store in.

Thereafter, the copying operation is performed according to the procedure shown in the flowchart of FIG. That is, from the job start address 22b stored in the job modification information memory 20,
A byte of data is read from the disk device 13 via the disk control unit 14 (reference numeral 31), the data is edited (reference numeral 32), and the capacity m stored in the job capacity 22a of the job modification information memory 20 is When the editing process for =N×a bytes is completed (reference numerals 33 and 34), the job capacity is reset in the job capacity setting counter 22c until the copy number setting counter 22d becomes 0 (reference numeral 3).
5 to 37), repeat the above operations to print multiple pages of data S times.

Effects of the Invention As explained above, the printing apparatus of the present invention stores a disk device capable of storing a large amount of data of multiple pages, and reduces the number of copies to be printed sent from a host computer. The print data is sent from the host computer only once by storing the information in the job modification information memory and outputting and printing the data stored in the disk device as many times as the number of copies specified in the printing device. This has the effect that a desired number of print data can be obtained with only one copy, thereby reducing the burden of print data transmission on the host computer and improving the efficiency of print data creation.
