PROBLEM TO BE SOLVED: To prevent the malfunction of a printer by generating the data row of plural commands, which does not contain a prescribed data row, when the received data string of the commands, which contains the prescribed data row. SOLUTION: When a data row is a picture printing command, it is checked whether the data row of a real time command is contained in the parameter part of the picture printing command or not (S604). When it is not contained, the data row of the printing command is transmitted to a printer (S605). When it is contained, a conversion processing is executed, the data row of the printing command is divided and the new data row of the printing commands is generated (S606). The processing of a step S604 to a step S606 on the new generated data rows of the printing commands are recursively executed and therefore all the data rows are processed (S607).
