Abstract

PURPOSE:To provide a printing control method of automatically changing a format in accordance with character data inside a printer by checking whether a format indicated by character data is the same as a format which is already set up in a format data storage memory when there are character data requiring a change of format, and if the format is different, executing rewriting of the format set up in the format data storage. CONSTITUTION:A format change discrimination mechanism 5 receives format data from a format data storage memory 3 and character data from a character data storage memory 4 at format B data signal and character B data signal 11 respectively. Then it is checked whether character data relative to format change is involved in the character B data signal 11. If there are any character data relative to format change, then it is checked whether a format indicated by detected character data concerning format change is the same as that which is already set up in the format data storage memory 3. If the format is different, the content of the format data storage memory 3 is to be rewritten into a content corresponding to a format designated anew.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a print control method, and particularly to a print control method in a printer device used as an output device of a computer.

[Conventional technology]

As a conventional print control circuit for this type of printer device, for example, Japanese Patent Application Laid-Open No. 60-22234, 6°-1
As described in Publication No. 40421, it has a memory for storing character data and a memory for storing format data, and reads and combines the data stored in both memories, stores it in an output buffer, and outputs it to the printing section. [Problem to be solved by the invention] In the print control circuit, for example, when a so-called control code such as change in line feed pitch, change in 9 character spacing, etc. is inserted as character data, this line break is In order to change the format by changing the pitch or the like, it is necessary to newly reset the format data in the printer device.

However, in the conventional print control circuit as described above, consideration has not been given to changing the format depending on the character data. There were serious problems such as an increase in the amount of waste.

The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in conventional print control circuits, and to eliminate the occurrence of insertion of character data that requires changing format data. Even though.

An object of the present invention is to provide a print control method that automatically changes the format corresponding to character data within a printer device.

[Means for solving problems]

The above-mentioned object of the present invention is to provide a print control circuit which has a memory for storing format data that can be set on a page-by-page basis, a memory for storing character data, and an output buffer 7 for storing a combination of the two. A format change determination means is provided between the memory and the character data storage memory, and the determination means inspects whether or not there is character data that involves a format change in the character data sent from the host device. If there is character data that requires a change, it is checked whether the R expression indicated by the character data is the same as the format already set in the format data storage memory, and if they are different, the R expression indicated by the character data is checked. This is achieved by a print control method characterized by rewriting the format set in the format data storage memory.

[Effect]

In the present invention, the print control circuit includes a format data storage memory for storing format data sent from a host, a character data storage memory for storing character data, a format change determination mechanism section shown below, and the above-mentioned format data storage memory for storing format data sent from a host. It has a combination output buffer unit that logically ORs the contents of the format data storage memory and the character data storage memory and stores the result in an output buffer.

The above-mentioned format change determination mechanism has a function of checking whether or not there is character data related to format change in one character data, and if the result of the check is that there is no character data related to format change, it does not change the contents of the format data storage memory. Function and also
It has a function of rewriting the contents of the format data storage memory when there is character data related to the format change.

This format change determination mechanism determines that if there is character data related to a format change and the contents of the format data storage memory are rewritten, the host will reset new format data or the character data related to the format change will be rewritten. The contents of the format data storage memory are held until new data is sent.

Therefore, in the present invention, when character data from a host whose format data needs to be changed is sent to the printer device, the format change is not ignored.

〔Example〕

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

FIG. 2 is a configuration diagram of a system comprising a host and a printer device, showing one embodiment of the present invention.

In the figure, 1 is a host, 2 is a printer device, 3 is a format data storage memory, 4 is a character data storage memory, 5 is a format change determination mechanism section, 6 is a combination output buffer section, and 7 is a printing mechanism section. .

In the figure, format data is set in the format data storage memory 3 of the printer device 2 by the format A data signal 8 from the host 1, and character data is set in the format data storage memory 3 of the printer device 2 by the format A data signal 8 from the host 1. 2 is input into the character data storage memory 4.

A flowchart of the above-mentioned processing by the format change determination mechanism unit 5 is shown in FIG. The processing by the format change determination mechanism section 5 will be described below with reference to FIG.

The format change determination mechanism section 5 includes a format data storage memory 3.
and character data from the character data storage memory 4 are received by a format B data signal 10 and a character B data signal 11, respectively (processing 21), and the format data is received in the character B data signal 11. Process 22) checks whether character data related to the change (for example, "line break pitch", etc.) is included, and if there is character data related to the format change, go to process 23), or if there is no character data related to the format change. If so, the process advances to process 26, which will be described later.

In process 23, it is checked whether the format indicated by the detected character data regarding the format change is the same as the format already set in the format data storage memory 3. If these are different, the process proceeds to step 24, where the contents of the format data storage memory 3 are rewritten to contents corresponding to the newly designated format. If they match, the process is ignored and proceeds to process 26, which will be described later.

After the rewriting of the contents of the format data storage memory 3 in process 24 is completed, it is checked whether processing of all character data has been completed or not (process 25), and if not, processes 21 to 25 are repeated. If it has been completed, the process proceeds to process 26 together with the processes from process 22 and 23, in which the contents of the format data storage memory 3 and the character data storage memory 4 are combined and stored in the output buffer 6. Output.

In the above process, if the received data contains character data related to format change, the format discrimination mechanism section 5 sends the corresponding format as format change data 12 to the format data storage memory 3, and stores the format data. Rewrite.

The format data in the format data storage memory 3 and the character data in the character data storage memory 4 are logically summed as a format C data signal 13 and a character C data signal 14, respectively, and stored in the combination output buffer 6, and then printed. It is sent as a data signal 15 to the printing mechanism section.

At this time, the contents of the format data storage memory 3 are stored in the host 1.
or reset the format data from the format determination mechanism section 5.
The contents of the character data storage memory 4 are retained as long as they are not rewritten with the format change data 12, and are deleted after the contents of the character data storage memory 4 are transferred to the combination output buffer 6.

A specific example of the format change executed by the format change determination mechanism section 5 will be described next.

For example, as shown in FIG. 3, the format data before the format change includes the format data of the horizontal ruled line A data 17 stored in the format data storage memory 3, and the format data of the one character D data 16 "IU.
.

In this state, the host 1 sends "line feed pitch change" and "tachitsu..." of the character E data 18 in FIG. 4 to the character data storage memory 4 as character data including format changes. Suppose that At this time, the format change determination mechanism unit 5 changes the horizontal ruled line A data 17 in the format data storage memory 3 to the horizontal ruled line A data shown in FIG. 19
Rewrite it as

This rewriting is performed by the procedure shown in FIG.

According to this embodiment, data regarding format changes is present in the character data. Regardless of whether or not the format is changed automatically on the printer device side,
This has the effect of reducing print control processing on the host side.
