US Patent 7839526 Reservation of secondary printing devices in a substitute printing system

A printing system includes printing apparatuses connected to a network. A control apparatus of the printing system may send a print job to each printing apparatus and instruct each printing apparatus to execute the print job. When a first printing apparatus is instructed to execute the print job, the control apparatus makes a substitute printing reservation. The substitute printing reservation is for a second printing apparatus to execute the print job instead of the first printing apparatus. The second printing apparatus is set to a waiting state in which the second printing apparatus waits to execute the print job instead of the first printing apparatus.
