Patent ID: 8154742

Claim:
A print control apparatus for communication with a server that stores a printed matter information ID, print data and status information indicating a print interrupting position in correspondence to each other, the print control apparatus comprising: a transmission unit constructed to transmit a user ID and a password to a server; a reception unit constructed to receive a list of printed matter information, if the user ID and the password transmitted by the transmission unit to the server are correct; an instruction unit constructed to, if the user issues a halfway printing ID based on the list of printed matter information received by the reception unit, transmit the halfway printing ID to the server, receive print data corresponding to the transmitted halfway printing ID from the server, and instruct printing of the received print data, wherein, if the user does not issue the halfway printing ID, the instruction unit transmits printed matter information ID to the server, receives print data corresponding to the transmitted printed matter information ID from the server, and instructs printing of the received print data; and a display unit constructed to, if an interruption instruction is given after the instruction unit instructs the printing, transmit print interruption information including a printed matter information ID and status information to the server, receive a halfway printing ID issued based on the transmitted print interruption information from the server, the halfway printing ID being different from the printed matter information ID included in the print interruption information, and display a screen for confirming the received halfway printing ID, wherein in response to a print-completion notification received from the print control apparatus, the server determines whether the printed matter information ID for the print-completion notification corresponds to the halfway printing, and deletes the halfway printing ID if the printed matter information ID corresponds to the halfway printing, and does not delete the printed matter information ID if the printed matter information ID does not correspond to the halfway printing.
