Printing system, printing apparatus, printing server and printing method

A printing apparatus, operable in a predetermined network, for receiving from a printing server a print job sent from a print request terminal to the printing server and performing printing corresponding to the print job, the printing apparatus comprise:

• an event detection portion for detecting an occurrence of a predetermined event;
• and
• an order change request portion for transmitting an order change request signal in cases where the event detection portion detects the event,
• whereby the order change request signal is used to change the order of the print order memorized in a serer-side queue.

A printing method, operable in a predetermined network, by which a printing apparatus receives a print job requested by a print request terminal via a printing server and processes the print job, thus performing printing corresponding to the print job,

• the printing method comprising the steps of:
• in the printing server, the printing server memorize temporarily the print job requested by the print request terminal into a first-in first-out type of server-side job buffer portion in the order of arrival of the print job, whereby a server-side queue for the print job is formed;
• in the printing apparatus, the printing apparatus transmits an order change request signal from an order change request portion in cases where an event detection portion detects a predetermined event;
• and
• in the printing server that receives the order change request signal, a server-side control portion changes the order of the print job memorized in the server-side queue in response to the order change request signal and transmits to the printing apparatus a particular print job read from the print job memorized in the server-side job buffer portion in the changed order of the print job.

A printing server, operable in a predetermined network, for memorizing temporarily a print job requested by a print request terminal and supplying the print job to a printing apparatus to make the printing apparatus perform printing corresponding the print job, the printing server comprising:

• a first-in first-out type of server-side job buffer portion in which a server-side queue for the print job is formed to temporality memorize the print job in the order of arrival of the print job requested by the print request terminal;
• and
• a server-side buffer control portion for changing the order of the print job memorized in the server-side queue in response to an order change request signal coming from the printing apparatus,
• thereby transmitting to the printing apparatus the print job read out from the server-side job buffer portion in the order of the print job memorized in the server-side queue.
