Abstract
Abstract The present invention provides a network peripheral sharing system comprising a computer network, at least one client computer connected to the computer network, at least one server computer connected to the computer network, and a network address table containing network addresses of server computers connected to the computer network. Each client computer has a peripheral searching program that searches peripherals connected to the computer network and each server computer has at least one connected peripheral. The peripheral serving program in the server computer provides information on the status of peripherals to the client computer and transmits the status message of the peripheral to the client computer after receiving a request from the user thus establishing a link between the client computer and the peripheral. The peripheral searching program in the client computer emits a search request based on network addresses contained in the network address table to search the available peripherals of the server computer. The computer network, or internet, may further comprise sub-networks wherein client computers send search requests to the sub-network to search the peripheral connected to a server computer within the sub-network.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
219 words
A network peripheral sharing system comprising: a computer network for transmitting information; at least one client computer connected to the computer network for transmitting and receiving information, each client computer having a peripheral searching program executed in it for searching peripherals connected to the computer network; and at least one server computer connected to the computer network for transmitting and receiving information, each server computer having at least one peripheral connected to it and one peripheral serving program executed in it for providing a status message of each connected peripheral to a client computer, handling requests to change the status message of a peripheral, changing a status message of a peripheral to locked, and establishing a communication link between a client computer and one peripheral connected to the server computer; wherein a user can send a search request to search an available peripheral connected to one server computer by using the peripheral searching program of a client computer, and the peripheral serving program of each server computer will transmit the status message of the connected peripheral to the client computer after receiving the search request, and the peripheral searching program of the client computer can establish a communication link between the client computer and the peripheral of the server computer through the peripheral serving program of the server computer.
Claim 2
Dependent Claim
219 words
A network peripheral sharing system comprising: a computer network for transmitting information; at least one client computer connected to the computer network for transmitting and receiving information, each client computer having a peripheral searching program executed in it for searching peripherals connected to the computer network; and at least one server computer connected to the computer network for transmitting and receiving information, each server computer having at least one peripheral connected to it and one peripheral serving program executed in it for providing a status message of each connected peripheral to a client computer, handling requests to change the status message of a peripheral, changing a status message of a peripheral to locked, and establishing a communication link between a client computer and one peripheral connected to the server computer; wherein a user can send a search request to search an available peripheral connected to one server computer by using the peripheral searching program of a client computer, and the peripheral serving program of each server computer will transmit the status message of the connected peripheral to the client computer after receiving the search request, and the peripheral searching program of the client computer can establish a communication link between the client computer and the peripheral of the server computer through the peripheral serving program of the server computer.
Claim 3
Dependent Claim
48 words
