Controls the entire image forming apparatus 1. The communication unit 12 receives various data transmitted from the client PC 2 and transmits various data to the client PC 2 via the network. The communication control unit 13 causes the communication unit 12 to receive data and causes the communication unit 12 to transmit data. The storage unit 14 is the communication unit 1.
Store the data received via 2. The display unit 15 is
Based on the print control data received by the communication unit 12,
The user name, file name, paper size, number of prints, etc. are displayed. The image forming processing unit 16 prints out the print data received by the communication unit 12.

The client PC 2 has a main control unit 21, a communication unit 22, a communication control unit 23, a storage unit 24, a display unit 25,
And an input unit 26 and the like. The main controller 21 controls the entire client PC 2. The communication unit 22 receives various data transmitted from the image forming apparatus 1 and transmits various data to the image forming apparatus 1 via the network. The communication control unit 23 causes the communication unit 22 to receive data and causes the communication unit 22 to transmit data. The storage unit 24 stores various data. The display unit 25 displays print data.
The input unit 26 inputs various data.

The image forming apparatus 1 can have only a predetermined code page among a plurality of code pages, and displays a target character string on the display unit 15 based on the character code of the predetermined code page. On the other hand, the client PC 2 can have a plurality of code pages, select an arbitrary code page from the plurality of code pages, and target character string based on the character code of the selected code page. , For example, to generate print control data.

The printout based on the print data will be described. Print data is transmitted from the communication unit 22 of the client PC 2, and the transmitted print data is received by the communication unit 12 of the image forming apparatus 1 via the network. The received print data is stored in the storage unit 14, and the image forming processing unit 16 prints out based on the print data stored in the storage unit 14.

At the time of the above-mentioned printout processing, a character string is displayed on the display unit 15 of the image forming apparatus 1 based on the print control data transmitted from the client PC 2. The character string displayed here includes, for example, a user name, a paper size, and the number of prints. About the display process of these character strings. Hereinafter, description will be made with reference to the flowchart shown in FIG.

First, the client PC 2 inquires of the image forming apparatus 1 about the type of code page assigned in the image forming apparatus 1 (ST1). That is, the call for inquiry is output from the communication unit 22 under the control of the communication control unit 23 of the client PC 2.

This call is received by the communication section 12 of the image forming apparatus 1. In response to this call, the image forming apparatus 1 notifies the client PC of the type of code page assigned in the image forming apparatus 1. (ST2). That is, the communication control unit 13 of the image forming apparatus 1
Under the control of, the communication unit 12 outputs a response to the inquiry.

The client PC receives this response,
The type of code page assigned in the image forming apparatus 1 is recognized (ST3). When the type of code page assigned in the image forming apparatus 1 and the type of code page assigned in the client PC 2 match (ST4, YES), the code page selected in the client PC 2 The print control data represented by the character code is transmitted from the client PC 2 to the image forming apparatus 1 (ST
6). The transmitted character code is received by the image forming apparatus 1, and print control data based on this character code is displayed on the display unit 15 (ST7). Since the type of code page assigned in the image forming apparatus 1 and the type of code page assigned in the client PC 2 match, the character code transmitted from the client PC 2 is displayed on the display unit of the image forming apparatus 1. It is displayed correctly as the target character string in 15.

When the type of code page assigned in the image forming apparatus 1 is different from the type of code page assigned in the client PC 2 (ST4, NO), the client PC 2 tells the image forming apparatus 1 that the type is different. The desired character code to be transmitted is corrected (ST5). Examples of correction methods include the following methods. There is a first method in which the desired character code transmitted from the client PC 2 to the image forming apparatus 1 is re-expressed by the character code of the code page assigned in the image forming apparatus 1. Or client PC2
The desired character code to be transmitted from the image forming apparatus 1 to the image forming apparatus 1 is re-expressed with a character code common to both the code page assigned in the image forming apparatus 1 and the code page selected in the client PC 2. There is a second method. Alternatively, the client P
There is a third method in which the desired character code transmitted from C2 to the image forming apparatus 1 is replaced with the character code of the code page assigned in the image forming apparatus 1.

First, the above-mentioned first method will be described. In the case of the first method, the same code page as the code page assigned by the image forming apparatus 1 is reselected by the client PC 2 and is printed based on the character code included in the reselected code page. The control data is regenerated. That is, the code page assigned to the image forming apparatus 1 and the client PC 2
The target character string is sent after matching the code page selected in. As a result, the type of code page assigned in the image forming apparatus 1 and the type of code page assigned in the client PC 2 match, so that the character code transmitted from the client PC 2 is the same as that of the image forming apparatus 1. It is correctly displayed as the target character string on the display unit 15.

Next, the above-mentioned second method will be described. In the case of this second method, the code page assigned to the image forming apparatus 1 and the client PC 2
The print control data is regenerated with only the character code common to both the code pages selected in (1) and (2). The ASCII code is known as a character code common to all code pages. For example, a number can be expressed by the character code common to all code pages. In other words, the print control data expressed only by numbers (such as “0001” as the user name) is assigned to the code page and the client PC in the image forming apparatus 1.
2 is different from the code page selected in 2, the character code (for example, 0001 is expressed) transmitted from the client PC 2 is displayed in the display unit 15 of the image forming apparatus 1.
Is correctly displayed as the target character string (for example, 0001).

Next, the above-mentioned third method will be described. In the case of the third method, the code page assigned to the image forming apparatus 1 and the client PC 2
Both of the code pages selected in 1 are not changed, and the character string of the print control data expressed by the character code of the code page selected in the client PC 2 is the character of the code page assigned in the image forming apparatus 1. It is replaced by another string represented by the code. The replacement rule will be set in advance.
As a result, the character string of the print control data expressed by the character code of the code page selected by the client PC 2 is expressed as another character string by the character code of the code page assigned by the image forming apparatus 1. . As a result, the character code transmitted from the client PC 2 is described as another character string that plays a role in the image forming apparatus 1.

The character code corrected by the above-described correction method is transferred from the client PC 2 to the image forming apparatus 1.
(ST6), and the print control data is displayed on the display unit based on this character code (ST7).

In the conventional network print system, when the type of code page selected by the device on the character code transmitting side and the type of code page assigned by the device on the character code receiving side are different, character code transmission is performed. The character string based on the character code sent from the device on the other side might not be displayed correctly on the device on the side receiving the character code. Such a case occurs, for example, when a character code transmitting side device (client PC) brought in from home country is connected to a character code receiving side device (image forming apparatus) in another country via a network during an overseas business trip. easy. In such a case, it is desired to investigate the cause and avoid the troublesome work of changing various settings. The language notation system and language notation method of the present invention are
When applied to a network print system, the above-mentioned conventional problems can be solved. That is, even if the type of code page selected by the device on the character code sending side and the type of code page assigned by the device on the character code receiving side are different, the device is sent from the character code sending side. It is possible to prevent the character code from being garbled into a meaningless character string on the device receiving the character code.

The invention of the present application is not limited to the above-described embodiment, and can be variously modified at the stage of implementation without departing from the scope of the invention. In addition, the respective embodiments may be combined as appropriate as much as possible, in which case the combined effects can be obtained. Further, the embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in the embodiment, the problems described in the section of the problem to be solved by the invention can be solved, and the effects described in the section of the effect of the invention If you get
A configuration in which this component is deleted can be extracted as an invention.
