Method of transmitting changed printer information in real time and network printer using the same

A printing network which transmits changed printer information, comprising:

• a network printer;
• 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.

A method of changing first printer information set in a host, the method comprising:

• transmitting a set information request packet to a network printer;
• receiving a set information response packet including second printer information corresponding to the set information request packet from the network printer;
• comparing the first printer information with the second printer information;
• and
• changing the first printer information into the second printer information if the first printer information is not the same as the second printer information.

A method of changing printer information, the method comprising:

• receiving first printer information transmitted from a network printer;
• comparing the first printer information with second printer information stored in a host;
• and
• changing the second printer information into the first printer information according to the compared result.

A method of changing printer information, the method comprising:

• receiving changed printer information in a host when printer information of a network printer changes;
• comparing printer information set in the host with the changed printer information;
• and
• changing the printer information set in the host into the changed printer information according to a result of the comparing.

A method of changing printer information set in a host of a network printer, the method comprising:

• receiving changed printer information in the host when printer information of the network printer changes;
• comparing printer information set in the host with the changed printer information;
• and
• changing the printer information set in the host into the changed printer information according to a result of the comparing,
• wherein the printer information set in the host is maintained to be accurate throughout a printing operation of the network printer.
