Abstract: 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.

Abstract: Disclosed is an image forming system comprising a first device and a second device connected to a network, and having an output permission and result notification function for image data stored in the first device. The system comprises a control unit for transferring a request for approval of the first device to the second device and transferring to the first device a response of the second device to the request for approval, and transforming the image data into a printable format and outputting the transformed image data. The request of approval requests an approval of the second device for printing of the image data. The image data is transferred to the control unit from the first device in response to an output permission in the response of the second device. The system comprises a printing unit for printing on a print paper an image corresponding to the transformed image data.

Abstract: A network image forming apparatus includes a communication part to communication-interface with at least one user terminal, a print engine part to print print data transmitted from the at least one user terminal, an error detector to detect the presence of an error by checking an operating status of the print engine part and to generate an error code corresponding to the kind of the detected error, a URL information generator to generate URL information on a web page that provides solution information corresponding to the error code, and a controller to control the communication part to transmit the URL information generated by the URL information generator corresponding to the error code to the user terminal that has requested a print job.

Abstract: A method for controlling the order of print operations for a printer comprises the following steps of: determining whether a printer engine is performing a print operation if print operation information has been received from one or more computers connected to a network; storing the print operation information if the printer engine is performing the print operation; requesting a computer that has transmitted the print operation information to transmit print data if the printer engine is not performing the print operation, and initializing a counter if the print data is received from the computer; counting a print time period and determining whether the counted time period exceeds a predetermined print time period; detecting print operation information, which satisfies a predetermined condition, from stored print operation information if a counted time period exceeds a predetermined print time period; stopping temporarily the print operation for the print data transmitted from the computer if the print operati

Abstract: An interface apparatus and method of interfacing an external user with at least one data processor having at least one port. The apparatus determines whether the user's data transceiving with the data processor in a packet is authenticated and/or authorized, using the packet received from the user. The data provided from an authenticated and/or authorized user is transmitted to the data processor or the data provided from the data processor is transmitted to the authenticated and/or authorized user, if it is determined that the user's transceiving of data with the data processor is authenticated and/or authorized. Therefore, an authenticated and/or authorized external user can use a corresponding data processor or remotely check a state (e.g., a trouble state) of the data processor in advance or in real-time without setting specific software in the interface apparatus. Further, unnecessary advertising pamphlets and leaflets can be prevented from being printed by the external user.
