If a print job is designated to interrupt print, processing of any print job currently being processed is interrupted, print processing of the instructed print job is immediately performed and resumption of the interrupted print job is automatically performed afterward. Further, if an interrupt print occurs, the sending source of the interrupted print jobs (host computers, etc.) are notified that an interrupt occurred.

Print control apparatus, print control method, memory medium for storing print control program, and print control program

A server obtains an adaptivity of a selectable device for a device retrieval condition from a client and sends it to the client. The client presents the adaptivity to the user, thereby enabling the user to freely select a desired device among a plurality of devices which conform with the retrieval condition.

When an engine detects changes in condition such as a power-OFF operation, an out-of-paper state, or the like, it sends a condition change signal indicating that the condition has changed to an engine control unit. The engine control unit inquires of the engine as to the contents of the changes in condition using a command signal so as to examine the cause of the changes in condition. When a power supply is scheduled to be turned off, a message indicating it is supplied to a host computer that uses the printer, or job conditions are saved, and the host apparatus is informed of the saved job conditions after the power supply is turned on again. In the case of the out-of-paper state as well, a message indicating it is supplied to the host computer that uses the printer. The items to be informed can be selected from the host computer.

Printing apparatus and its control method

A calibration for the printing apparatus is performed under relatively easy management by a host computer and then the printing apparatus always can perform printing in a condition where an appropriate calibration is made for the printing apparatus. More specifically, the printer holds calibration data downloaded from the host computer and executes a density control (S) which generates calibration data at a predetermined timing independently in the printer. Then, the printer checks whether a difference between a print density value represented by the calibration data generated in the printer and a print density value represented by the calibration data held is greater than a predetermined threshold value (S). When the difference is greater than the predetermined value, the printer notifies an error (S) and sets a correction table based on the calibration data generated by the printer (S).

Printing apparatus and calibration control method

A printing apparatus having a plurality of print modes and a plurality of paper feeding means is constructed by means for designating the print mode, means for selecting the paper feeding means, and means for discriminating whether a print medium corresponding to the designated print mode coincides with a print medium corresponding to the selected paper feeding means or not.

Apparatus and method for selecting print media and feed tray independently

In the case where since there is no recording paper in an upper stage cassette in which recording papers of an optimum size (for example, A4 size) should be enclosed, a lower stage cassette in which recording papers of another size are enclosed is used as a temporary paper feeding unit and a paper feed is performed, whether there is a status change such as supply of recording papers, removal of output papers from a paper ejecting unit, or the like or not is discriminated on the basis of a status change signal, whether the recording papers of the A4 size have been supplied to the upper stage cassette or not is discriminated, and whether an automatic paper feeding mode has been set or not is discriminated. Thus, when the recording papers of the A4 size are supplied to the upper stage cassette and the automatic paper feeding mode has been set, the paper feeding unit is switched from the lower stage cassette to the upper stage cassette.

Printing apparatus with a plurality of paper feeding units and controls of same

Print control apparatus has a holding unit that hold plural pieces of received print information. If an error during a printing process for one of the plural pieces of print information is detected, it is determined whether the detected error is of a first type or a second type. The printing process of the plural pieces of print information is controlled such that the printing process of any of the plural pieces of print information is interrupted if the detected error is of the first type. If the detected error is of the second type, the printing process is interrupted for the one piece of print information but is continued for another of the plural pieces of print information.
