Claims (4)

A print processing method for performing print processing by converting transmission data transmitted from a print processing requesting device into print data by a conversion unit and outputting the data to an output device,
Said transmission data and said transmission data holding stored in the storage means the printing data converted by said converting means,
When an identifier indicating that there is a history of requesting print processing from newly transmitted print data is detected,
Previously said reads the transmission data and the print data that are stored before term memory unit,
A difference between the new print data and the previous print data is determined for each print page ;
The determination result in the transmission data to which the newly transmitted based converted into print data by the printing page units, performs print processing replaced with the destination of the print data,
A print processing method characterized by the above. A print control device that converts transmission data transmitted from a print processing requesting device into print data by a conversion means and outputs the print data to an output device,
Storage means for sequentially storing the transmission data and print data obtained by converting the transmission data by the conversion means;
Detecting means for detecting the identifier when the identifier indicating that the newly transmitted transmission data already has a history of requesting the printing process is provided;
When the detection unit detects the identifier, the transmission data stored in the storage unit is searched based on the newly transmitted transmission data, and the print data is stored together with the previous transmission data. Search means to read,
Determining means for determining a difference between the newly transmitted transmission data and the previous transmission data for each print page;
Based on the determination result of the determination means, the newly transmitted transmission data is converted into print data by the conversion means, and the print data is replaced for each print page and output to the output device. Output control means;
Print controller you comprising a. Including a creation means for creating an identifier to be added to transmission data at the next print processing request from the detection result of the detection means, and the storage means for transmission together with the identifier so that the search means can search based on the identifier. The print control apparatus according to claim 2 , wherein data and print data are stored . 3. The determination unit according to claim 2, wherein when the editing data for the previous transmission data is added to the newly transmitted transmission data, the determination unit makes a determination based on the editing history. The printing control apparatus according to 3.
