[Industrial application field]

The present invention relates to a data transfer speed setting method for print control in which a computer system that controls a printer to print data sets the data transfer speed required for printing. be.

The standard data transfer speed for data transferred from a computer system to a printer is 120.
Q bPS, 2400 bPS, 48QObPs,
Something like 9600 bPS is used. From now on, printers on the market will be able to freely set these data transfer speeds using short pins, etc., in order to provide versatility.

Therefore, when a computer system controls a printer and prints data, it checks the preset blink data transfer rate setting value and uses this to set the data transfer rate of its own data transfer control device. There is a need to match them.

[Conventional technology]

Conventionally, one user checks the printer's data transfer speed setting by visually checking the printer's printed board and checking the settings of the short bin, etc., and inputs the confirmed data transfer speed setting into the computer system as a parameter. As a result, the data transfer rate was set for print control in the computer system.

[Problem to be solved by the invention]

However, with this conventional technology, there are problems in that it takes time to set the data transfer rate because it is done manually by the user, and there are many setting errors. In order to check the printer's transfer speed setting, if the printer is integrated with a computer system, it is necessary to turn off the computer system's power and pull out the printed circuit board, making it difficult to operate the computer system. There was also the problem that it significantly deteriorated the sex.

The present invention has been made in view of the above circumstances, and provides data that enables the setting of the data transfer rate for print control in a computer system to be automatically, quickly and accurately without the need for manual work by the user. The purpose is to provide a transfer rate setting method.

According to the present invention, the transfer rate setting means 11 (- sets the data transfer rate value according to the priority order stored in the priority information storage means 12, and transfers the test data stored in the test data storage means 13 to the printer 20. Then, when the status information detection means 14 detects the status information returned as a response to the reception of the test data, the transfer speed setting means 11 prints the data transfer speed value returned from the status information. It operates to set the data transfer rate setting value for.

As described above, according to the present invention, it is possible to automatically set the data transfer rate without requiring any user intervention, and the data transfer rate in a computer system can be set extremely quickly and accurately. It will be done.

〔Example〕

Hereinafter, the present invention will be explained in detail according to examples.

FIG. 2 shows a system configuration diagram of the present invention. As shown in this figure, the computer system 10 includes a memory 1 that stores data to be printed on a printer 20, and an editing program 2 that edits the data stored in the memory 1 into print data.

It is composed of a data transfer control device 3 that operates to transfer the print data edited by this editing program 2 to the printer 20 and to receive status information returned from the printer 20 as a response to the reception of the print data. It is something.

In the present invention, the editing program 2 is configured to receive and receive status information detection information from the data transfer control device 3, and executes processing for setting the data transfer rate required by the data transfer control device 3. It is. This setting process sets the predetermined test data to 1200 bPs, which is used as the standard data transfer rate, 24
00 bPS, 4800 bPS.

This is executed by sequentially transmitting the status information to the printer 20 at 9600 bPS and determining the data transfer rate at which the status information is returned from the printer 20.

Next, details of the setting process of the present invention will be explained according to the flowcharts shown in FIGS. 3 and 4.

First, as shown in step 1 of the flowchart of FIG. 3, the 1 editing program 2 sets the data transfer rate of the data transfer control device 3 to a predetermined value. The value to be set at this time is preferably 4800 bPS, which is the most commonly used data transfer rate setting value for the printer 20.Next, in step 2, &I collection program 2. Test data to be sent to the printer 20 is output to the data transfer control device 3. This test data is preferably blank data to prevent it from being actually printed on the printer 20.

Once the data transfer rate and test data are set in this way, the data transfer control device 3 executes a process of transferring the test data to the printer 20 at the set data transfer rate, as shown in step 3. . As a result of this test data transfer, if the data transfer rate set in step 1 matches the data transfer rate setting value of the printer 20, the printer 20 can be transferred within a predetermined time.
The status information of the data reception response will be returned. From now on, the data transfer control device 3 will wait for the status information to be transferred for a predetermined time in step 4.

In the subsequent step 5, the editing program 2 determines whether the data transfer control device 3 has received the status information within this predetermined time, and if the status information has been received, in the next step 6, the editing program 2 determines whether or not the data transfer control device 3 has received the status information. judge whether it is correct or not.

When the status information is determined to be correct in step 6, the data transfer rate set in step 1 matches the data transfer rate setting value of the printer 20, so the attribute collection program 2 is stored in the memory 1. The stored data is edited into print data, and this print data is transferred to the printer 20 via the data transfer control device 3.

On the other hand, when it is determined in step 5 that the status information has not been transferred, or when it is determined in step 6 that the status information is not correct, the data transfer rate set in step 1 is the data transfer rate setting of the printer 20. Since the value does not match, proceed to step 7 and select a new data transfer rate, and use this selected data transfer rate to proceed to steps 1 to 6.
The process will be repeated.

FIG. 4 shows a detailed flowchart of this step 7. In this flowchart, the data transfer rate set in step 7 is 4800bPS-9600bp.
The priority order is s→2400 bPS→1200 bPS. The reason for this prioritization is that the data transfer speed can be set in a shorter time by trying the settings in order of frequency of use. It goes without saying that the present invention is not limited to this priority order.

In this way, by repeating the processing from step 1 to step 7, the data transfer speed setting value of the printer 20 can be detected, and the data transfer speed of the computer system 10 can also be automatically set to this value. It becomes.

For a detailed explanation of the invention, FIG.
