Method of transmitting changed printer information in real time and network printer using the same
View Patent ↗A method of transmitting printer information which can inform a host of changed printer information in real time whenever printer information changes and a network printer using the method. The method includes determining whether or not the printer information has changed and transmitting the changed printer information in real time to a communications network or a predetermined program which communicates with the network printer. The network printer includes a printer information change determination circuit which determines changes in printer information, and a changed information notification module which transmits in real time the changed printer information to a communications network or a predetermined program which communicates with the network printer. The changed information notification module transmits the printer information to the communications network or the predetermined program when the network printer is turned on.
1. A method of informing a host connected to a network printer of information which the host needs to use in order to communicate with the network printer, the method comprising:
receiving printer information, transmitted from the network printer, in the host, wherein transmission of the printer information from the network printer to the host is initiated by the network printer without a request from the host;
comparing printer information set in the host with the received printer information; and
changing the printer information set in the host according to the received printer information if the printer information set in the host is different from the received printer information,
wherein the received printer information includes information which is required by the host to establish subsequent communication with the network printer.
2. The method of claim 1 , wherein the changing comprises changing the printer information set in the host into the changed printer information in real time.
3. The method of claim 1 , wherein the received printer information, transmitted from the network printer to the host, comprises an IP address associated with the network printer, which has been recently changed.
4. The method of claim 1 , wherein the received printer information, transmitted from the network printer to the host, comprises subnet mask information associated with the network printer, which has been recently changed.
5. The method of claim 1 , wherein the received printer information, transmitted from the network printer to the host, comprises gateway information associated with the network printer, which has been recently changed.
6. A method of informing a host connected to a network printer of information which the host needs to use in order to communicate with the network printer, the method comprising:
receiving printer information, transmitted from the network printer, in the host, wherein the transmission of the printer information from the network printer to the host is initiated by the network printer without a request from the host;
comparing printer information set in the host with the received printer information; and
changing the printer information set in the host according to the received printer information if the printer information set in the host is different from the received printer information,
wherein, prior to the changing of the printer information set in the host according to the received printer information, the printer information set in the host is maintained in a memory of the host throughout at least a subsequent printing operation of the network printers; and
wherein the received printer information includes information which is required by the host to establish subsequent communication with the network printer.
7. The method of claim 6 , wherein the received printer information, transmitted from the network printer to the host, comprises an IP address associated with the network printer, which has been recently changed.
8. The method of claim 6 , wherein the received printer information, transmitted from the network printer to the host, comprises subnet mask information associated with the network printer, which has been recently changed.
9. The method of claim 6 , wherein the received printer information, transmitted from the network printer to the host, comprises gateway information associated with the network printer, which has been recently changed.
