Abstract
A network peripheral support method including a client with a general purpose software capability and a server connected to the peripheral. The server of the present invention waits for a client to attempt to open a connection with the peripheral. The client sends a peripheral connection request via a data packet to the server, and the server accepts the connection. The server determines an availability of the peripheral and locks the peripheral so that it cannot be used by other clients. Thereafter, the server opens a connection with the peripheral, if it is available, and notifies the client of the peripheral availability. The server then waits for predetermined data from the client, which when received, results in the client having control of the peripheral for at least a first predetermined time period, and when received sends the data to the client. The server closes the connection with the client upon completion of sending the data to the client.
