Description

The present invention relates to a control system for an information processing peripheral device.

[Conventional technology]

Conventionally, a user has made a user program by fully knowing whether or not the information processing peripheral device to be used has an additional function.

For example, when the user program is intended to print a form to a printer which is an information processing peripheral device through a print object creating means, the printer has various hardware or firmware additional functions, and the additional functions If the user program requests a non-existent operation, the printer will detect an error and stop working, or a distorted form will be printed. In this case, the user analyzes the error, corrects the user program, and re-executes it.

[Problems to be solved by the invention]

In the above-mentioned conventional method, since the information processing peripheral device discovers an error, the cause classification display is unclear, it takes time to analyze the error, the program needs to be modified, and the user cannot Has the drawback that it requires complicated knowledge of
In addition, there is a drawback that the check can be performed only by occupying the device, and in a system that performs virtual I / O, an error is found in the actual device after the user program ends, so the type of error depends on the user program. There are drawbacks that are not reported.

[Means for solving problems]

The system of the present invention exists between the information processing peripheral device and a user program for input / output separately from the both, has a storage area for the additional function of the information processing peripheral device, and stores the additional function. Storage means and reading means for reading the additional function from the information processing peripheral device and storing it in the additional function storage means;
Analyzing means for inputting a user program and analyzing the additional function use request of the information processing peripheral device, and additional function requested of the additional function of the information processing peripheral device in the storage area and the analysis result by the analyzing means. And a notifying means for notifying from the comparing means whether or not the user program requests an operation which the additional function does not have.

In this way, the additional functions of the information processing peripheral device are stored in advance, the user program is analyzed when the information processing peripheral device is initialized, the analysis result is compared with the stored contents, and the user program becomes the additional function. By checking whether or not the user does not request an operation that is not required and notifying the user, it is possible to avoid a situation in which the user program requests an operation not included in the additional function and the information processing peripheral device does not operate. No need to analyze user error.

〔Example〕

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

FIG. 1 is a block diagram showing an embodiment of an information processing peripheral device additional function check system of the present invention.

The present embodiment is an example of application to a printer and a print range expansion addition function.

The printer 5, as shown in FIG.
Normally, up to n rows in the vertical direction and m digits in the horizontal direction can be printed with the upper left corner as the base point, but up to 1 digit in the horizontal direction can be printed because of the function to expand the printing range in the horizontal direction. The reading means 7 operates when the printer 5 is powered on and an initial operation is performed, and it is read that the printer 5 has only the additional function of expanding the horizontal print range, and the printable area is n. It is calculated that the line has 1 digit, and the additional function storage means 8 is informed that the device is the printer 5 and the values of n and l. (Store). The additional function storage means 8 has a storage area as shown in FIG. 3, secures an area for the print 5, sets the printable area values n and l, and sets the other additional functions to “none”. "Set. A print image as shown in FIG. 4 is written in the user program 2. In this case, the print area defined by the user program 2 is Y rows and X columns, but the actual form image is used up to y rows and X columns. The user program 2 also includes information about printing on the printer 5. The analysis unit 6 inputs the user program 2, analyzes that the target information processing peripheral device is the printer 5, and defines the applied area of Y rows and X digits, and the area to be actually printed. Is analyzed for y rows and x digits. The comparing means 9 inputs these analysis results, refers to the additional function storing means 8 for the information of the additional function when the device type is 5, and as shown in the flowchart of FIG.
Compare x and Y, X with n, l. That is, first, y> n
Alternatively, x> l, that is, it is determined whether the print content is out of the printable area (process 11). If it is out, it is determined that "printing is impossible" (process 12). If not, Y> n or X> l, that is, it is determined whether the defined print area is out of the printable area (Processing 13), and if so, the "correction print" of correcting the defined print area to n lines or l columns A determination is made (process 14), and if not output, a "normal print" is determined (process 15). If the determination result of the comparison means 9 is "printing is not possible", the notification means 10 issues an instruction to stop printing to the object creation means 3 and the user 1
Informs you that printing is not possible and the contents of the error, and clicks "Correct print"
In the case of, a partial correction instruction is issued to the object creating means 3, and the correction content of the user 1 is notified, and in the case of “normal printing”, the user 1 is notified that normal printing is possible.

〔The invention's effect〕

As described above, according to the present invention, the additional function of the information processing peripheral device is read and stored, the user program is checked, and this is compared with the stored content,
There is an effect that the user can create a program without being aware of the restrictions of the hardware or the firmware, and the situation where the information processing peripheral device does not operate can be avoided.
