Abstract: When a network printer receives print data appended with related data from a client device via a network (S11), the related data is separated from the print data (S12) and stored in a predetermined region of a hard disk (S13). The print data is stored in the hard disk (S14) in correspondence with the related data. Then, printing is executed to print out the print data (S15). When a user requests display of the related data (S16:YES), the related data is displayed on a display (S17). The related data includes related image data and management data. When a user requests printing of the related data (S18:YES), a printer engine prints out the related data (S19). In this way, the user can select desired print data in a short period of time.

The operating unit is capable of selecting one of the first selection item and the at least one second selection item.

Abstract: A duplicate setting prevention system for an image processing apparatus includes a setting file, a set of history information, a determination unit, a setting unit, a prohibiting unit, and a history information recording unit. The setting file is stored in a removable memory removably mounted on an image processing apparatus and is for setting the image processing apparatus. The set of history information is stored in the removable memory and indicates that the image processing apparatus has been set based on the setting file. When the removable memory is mounted on the image processing apparatus, the determination unit reads out the history information set and determines that a setting has been performed to the image processing apparatus based on the setting file. The setting unit performs the setting to the image processing apparatus based on the setting file.

Abstract: A peripheral device has a mounting portion and a storage unit. The mounting portion is configured to mount a removable storage. The storage unit is configured to store data.

Abstract: When a network printer receives print data appended with related data from a client device via a network (S11), the related data is separated from the print data (S12) and stored in a predetermined region of a hard disk (S13). The print data is stored in the hard disk (S14) in correspondence with the related data. Then, printing is executed to print out the print data (S15). When a user requests display of the related data (S16:YES), the related data is displayed on a display (S17). The related data includes related image data and management data. When a user requests printing of the related data (S18:YES), a printer engine prints out the related data (S19). In this way, the user can select desired print data in a short period of time.

Abstract: A setup is provided that enables strict management of licenses, without any incorrect use of license-requiring data if a communications failure should occur, in a configuration in which an image forming device acquires and uses license-requiring data from a server device. The configuration is such that a server device and a printer are connected, together in a mutually communicable manner, and the printer acquires license-requiring data that necessitates a license for use from the server device. If it has been confirmed that the communications state between the server device and the printer has failed, license-requiring data that is stored in a memory is deleted, thus inhibiting the printer, from using that license-requiring data for printing.

Abstract: In an image forming system in which a printing device is communicably connected to a server and a terminal, an automatic determination is performed to determine whether or not print data created by the terminal needs to be stored in a memory for placing the data in a reprintable condition. The print data stored in the memory can be reprinted without need for resending the same print data from the terminal or server to the printing device. The automatic determination is, for example, performed by referring to the header of the print data and determining whether the print data is from the terminal or the server.

Abstract: Image patterns formed on a sheet of paper changes in correspondence with an input image density. As the input density increases, the image patterns change from the state of FIG. 6(a) through the state of FIG. 6(b)-6(g) to the state of FIG. 6(h). As apparent from the drawings, as the input density increases, the linear patterns will extend in a direction parallel to the sheet conveying direction A. Even when mechanical oscillation occurs in the sheet conveying direction A, no changes in tone will appear. When the input density further increases from the state of FIG. 6(d), the linear patterns will grow both in leftward and rightward directions. Because each dither matrix is elongated in the sheet conveying direction A, the linear patterns will grow in the leftward and rightward directions only after the input density increases to some great value. It is therefore possible to effectively prevent occurrence of jitter.

Abstract: A printer including a print engine capable of printing images onto both the front surface and the backside surface of each recording paper. The printer operates as described below while counting, with the copy counter, the number of printed copies. The odd-numbered copy is printed on the front surfaces of the papers form the first page to the last page in this order and is discharged facing downwardly. The even-numbered copy is printed on the backside surfaces of the papers from the last page to the first page in this order an discharged facing upwardly. Accordingly, in the printed matter finally stacked on the discharge tray, the printed sheets are stacked so that the surfaces, on which images are printed, are alternated in the respective copies. In each copy, printed sheets are arranged properly from the first page to the last page in order.
