Abstract: A server is to obtain, from a mobile device, information indicating a content, sender information about a sender for a printing of the content and delivery of the printed content, and receiver information about a receiver of the printed content. The server is to convert the content into printable data of the content and perform a process to print and deliver a printed content to the receiver according to a printing of the printable data of the content to the printed content and a delivery of the printed content to the receiver.

Abstract: A method of transmitting contents stored in a mobile device may include displaying a list of the contents on a display screen, receiving a user input for selecting content to be printed, on the display screen, displaying a list of printers capable of printing the selected content, and a ‘send to delivery server’ item on the display screen, transmitting the content to a cloud server based on a user input for selecting the ‘send to delivery server’ item on the display screen, displaying a printing cost of the content on the display screen while the content is being converted into print data by the cloud server, receiving payment information of the printing cost and receiver information of a printout of the content, and transmitting the payment information and the receiver information to the cloud server.

Abstract: A fast printing apparatus and method thereof include a host converting job data for a print job into a printing code and analyzing and processing the printing code to produce a display list, and a printer temporarily storing the display list input from the host, producing bit map data by processing the temporarily stored display list, and printing a bit map image corresponding to the produced bit map data. With the use of the fast printing apparatus and method thereof, it is possible to increase a printing speed of the printer.

Abstract: Disclosed is a method for enhancing print quality by adjusting a print density of a printer according to changes in the environment. Threshold tables having different threshold values corresponding to different environments of a printer engine are stored in the printer and the printer itself can perform a halftone process. According to the method, print data to be printed are first received and stored when a print operation command is received. Then, present environmental state information is received from the printer engine. Corresponding to the present environmental state information, a threshold table is selected among the threshold tables. Thereafter, the lightness of the print data is determined through the selected threshold table and the halftone process is performed. Then, the print data that is image-processed through the halftone process is transmitted to the printer engine to be printed.

Abstract: A debugging device in an apparatus having a scanning and printing function includes: an input unit for inputting a defects tracing mode and for selecting a function; a facsimile machine driving unit for driving a facsimile machine to transmit and receive facsimile data and generated operating status messages of the facsimile machine; a printer driving unit for driving a printing unit to print data and generated operating status messages of the facsimile machine; a storing unit for storing the generated status messages; and a processing unit for replying a defects-generated job, storing the generated messages in the storing unit, and outputting the stored messages according to the selection of the function. The debugging device in an apparatus having a scanning and printing function generates status messages according to running states of the scanning and printing system. Generally, the generated messages are ignored in cases where defects are not generated.

Abstract: Disclosed is a method for processing graphic data in a laser printer capable of improving an effect of processing the graphic data, in which the graphic data are processed even though post-processing of the graphic data is not completed while pre-processing of the graphic data is performed. The method according to the present invention includes the steps of: processing low level graphic data which are inputted from a host computer to a laser printer to generate graphic elements; and generating and printing real bitmap image corresponding to a respective band on a recording paper during the feed of the recording paper after carrying out the pre-processing.

Abstract: Disclosed are a multifunctional apparatus equipped with a jam recovery device and a selective jam recovery method. The multifunctional apparatus has an image forming unit enabling the apparatus to record image data onto a recordable medium. The multifunctional apparatus can record two types of data. When a page of a first type of data is stored in a page queue processor of the multifunctional apparatus and starts to be recorded onto a first page of a recordable medium, the page queue processor deletes the page of the first type of data according to whether the first page of the recordable medium has been successfully discharged from the multifunctional apparatus and, importantly, also according to a condition of a discharge error recovery function.

Abstract: A data transmission method for a host and a data reception method for a multifunction device are disclosed. Data of one mode are received from the host even when the multifunction device performs in a specific mode and returns again to a previous mode after reception of the data in the one mode, thereby providing no damage to the operation in the previous mode. The data transmission method for a host connected to a multifunction device includes the steps of: detecting the mode of the multifunction device corresponding to data in response to a data transmission command to the multifunction device; transmitting a signal indicative of the detected mode to the multifunction device; and transmitting the data to the multifunction device after transmission of the signal.

Abstract: An image forming device using an engine for performing a print operation, an engine controller which determines the state of the engine and generates an engine state signal, and a video controller which receives the engine state signal and determines whether data transmitted from a computer is to be received or not based on whether the engine state signal is indicative of a normal state, an abnormal state which can be recovered from, and an abnormal state which can not be recovered from. Data to be printed is received from the computer when the engine state signal is indicative of a normal state and an abnormal state which can be recovered from; data to be printed is not received from the computer when the engine state signal is indicative of an abnormal state which can not be recovered from.
