During the performance of a printing command of an application program of a client being connected to a server, the printer status information is provided to the client so that the client can selectively use a variety of printer features. Additionally, printers are effectively managed and controlled so that a printing system has an improved operation speed. The printing system is controlled at a management server. In the printing system having the server, at least one client, and a plurality of printers, each being connected through a communication line, the server has the printer status information. Accordingly, in the performance of a printing command of the client, the client requests the management server for the transmission of the printer status information, receives the requested information, and indicates the received information through an indicating part according to a predetermined form. |
