As a user selects one of error recovery methods for each error category, and the selected method is stored in a memory. When an error occurs, an error recovery method corresponding to an error category of the error is detected. If the detected method is automatic print continuation, then the error is ignored and print operation is automatically continued. If the detected method is a recovery by user's operation, then an error message is displayed, and a procedure is performed in accordance with an instruction from the user.

A printing system includes a network, a first computer connected to the network, a second computer connected to the network, and a printer connected to the network. The first computer instructs the printer to print. The printer includes a printer controller and a printer engine. The printer controller includes an individual printer management part for managing the printer, and an individual printer information DB part. The second computer includes a total printer management service processing part for managing a plurality of printers including the printer connected to the network, and a total printer management information DB part. The second computer communicates with the printer controller and/or the first computer over the network to manage the printer to cope with trouble in the printer, order consumable items and replacement parts for the printer, and update programs and data for using the printer.
