A job management server, which is connected to a Web application server and a job processing apparatus via a network, comprises: a registration unit which registers, when a job received from the Web application server is added with information indicating that a request source of the job is the job processing apparatus, the job in a first job queue, and to register, when the job is not added with the information, the job in a second job queue having a lower priority than the first job queue; and a transmission unit which transmits the job registered in the first job queue in response to a request from the job processing apparatus while a user utilizes a Web application via the job processing apparatus.

A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

Whether to enable a packet discarding mode is designated and, if an information processing apparatus operates in a power saving mode and the packet discarding mode is enabled, the information processing apparatus determines processing for a received packet based on a proxy response pattern, a WOL pattern, and a discard pattern, and, if the information processing apparatus operates in the power saving mode and the packet discarding mode is disabled, the information processing apparatus determines processing for the received packet based on the proxy response pattern and the WOL pattern without using the discard pattern.

In an image forming apparatus a controller receives user instruction information for printing a test chart, controls a printer to print the test chart on a sheet regardless of a result of reading mode selection, controls a display to display a screen for selecting a reading mode for reading the test chart among a plurality of reading modes, and controls a conveyance roller and a reading sensor to read the test chart on the sheet while conveying a stacked sheet in a case where a first reading mode is selected on the screen. The controller also controls the reading sensor to read the test chart on the sheet on a platen in a case where a second reading mode is selected on the screen, and controls density of the image to be printed by the printer based on a reading result of the test chart by the reading sensor.

A print data processing system 101 has a plurality of print data distribution devices, and an information processing device that receives print data from the plural print data distribution devices. The information processing device initiates a reception process unit appropriately to the plural print data distribution devices. Each reception process unit queries the related print data distribution device for print data, receives the print data when print data is on the print data distribution device, and stores the received print data to a shared storage area.

A printing control apparatus connected to a printing apparatus operated in a standby state and a power saving state includes a reception unit that receives a printing request for causing the printing apparatus to execute printing, a generation unit that generates printing data in accordance with the printing request received by the reception unit, a determination unit that determines whether or not the printing apparatus is in the power saving state, and a transmission unit that transmits return data for returning the printing apparatus from the power saving state to the standby state before the printing data generated by the generation unit is transmitted in a case where the determination unit determines that the printing apparatus is in the power saving state, and does not transmit the return data in a case where the determination unit determines that the printing apparatus is not in the power saving state.

Ink supplies and methods to prepare an ink supply are disclosed. An example ink supply for a printer includes an ink chamber within a housing of the ink supply. The housing is removably installable within the printer. The ink chamber is to store ink. The ink supply further includes a machine readable storage medium to store a first priming parameter. The machine readable storage medium is carried by the housing of the ink supply. The first priming parameter has a value to cause the printer to configure a first priming procedure of the printer. The first priming parameter has precedence in configuring the first priming procedure over a first corresponding priming parameter stored in a second machine readable storage medium of a second ink supply installed in the printer.
