PURPOSE:To attain the automatic display of an output, by receiving a data to be printed in the midst of the off-line processing at a terminal equipment of 2-job operation system containing a printer. CONSTITUTION:A virtual print program 5 sets up flags 9 and 9' in response to an off-line program 7 and an on-line program 8 respectively and stores both flags in a state flag storing area 6 in case both programs 7 and 8 are working on a terminal equipment 2. When the data to be printed is received from an on-line job processing program 3 working on the computer 1, the off-line flag 9 is checked and a virtual print file 13 is provided on a DASD 12 if the flag 9 is set up. Thus the file 13 stores the received data. Then a printing command is sent to a printer 11 when the processing is through with the program 7.
