An information processing apparatus is communicably connected via a printing apparatus to an inspection apparatus configured to perform an inspection of a print product. Upon receiving a job execution instruction from a user, the information processing apparatus transmits, to the printing apparatus, a first job for registering a reference image to be used in the inspection and a second job for printing an image corresponding to the reference image on a recording sheet. In a case where the information processing apparatus receives the job execution instruction while the inspection apparatus is inspecting a print product that is produced by the printing apparatus that has executed the second job that precedes the first job and corresponds to a job execution instruction different from the job execution instruction, the information processing apparatus does not transmit the first job until the preceding second job is completed.

A printing apparatus includes a plurality of container units containing a recording material. In a case where it is determined that a container unit is lacking in the recording material when printing is executed based on print data, the printing apparatus moves the container unit determined to be lacking in the recording material to a replaceable position. In a case where the container unit determined to be lacking in the recording material is not a specific container unit among the plurality of container units and the printing based on the print data is canceled without replacing the container unit determined to be lacking in the recording material, the printing apparatus moves the specific container unit to a specific position in preparation for printing using the specific container unit.

When a sheet remains in a staying portion of a printer for executing alternating sheet feed duplex printing, a printer driver precedently transfers print data of a page to the staying sheet to the printer in page order different from order of pages to be normally transmitted upon alternating sheet feed duplex printing. Thus, when two-sheet stay alternating feed is executed in the duplex printing without providing a memory of a large capacity, even if a no-sheet error occurred in a sheet feeding portion, the staying sheet can be preferentially printed and ejected.

Information processing apparatus, print control method, storing medium, and program

It is an object of the present invention to shorten the time required to release an information processing apparatus such as a host computer from an output apparatus such as a printer when print information is transmitted from the information processing apparatus to the output apparatus. In step S501, print information is received. In step S502, it is checked whether information from another I/F is being processed. If YES in step S502, the print information is compressed and stored in a reception buffer. If NO in step S502, the flow directly advances to step S505 to store the print information in the reception buffer without compression.

Image output apparatus, image output system and information processing

An output apparatus and method receives first information from an external source, generates second information based on the received first information, and outputs the generated second information. The apparatus includes a selector for discriminating the received first information by comparing a code included in the first information with codes provided in a number of analyzers and for selecting one of the number of analyzers suitable for the first information. The apparatus also includes a controller for skipping the received first information when the selector can select no suitable analyzer, when no data is input for a predetermined time to an input interface via which the first information was received, or until the input interface is switched.

Output apparatus and method in which a suitable analyzer is selected for

A printing apparatus which shuts off the power supply to the apparatus, if a state in which the power supply to the apparatus is meaningless continues for a predetermined period, to prevent wasteful electricity consumption. When a LBP has an abnormality, an error processor detects the abnormality, executes a predetermined processing such as notification of the occurrence of error, and outputs error information to a power controller. The power controller determines whether or not the abnormal state has continued for a predetermined period. If the power controller determines the continuation of the abnormality for the predetermined period, it outputs a power-off instruction to a power. The power shuts off the power supply to the respective elements of the LBP.
