A data transmission apparatus includes a reception processing portion and a transmission processing portion. When an instruction to print data is input, the reception processing portion receives a selection operation to select a destination of the data from a printing apparatus that can print the data or a storage that can store the data. The transmission processing portion executes a first transmission process of sending a print job including the data to the printing apparatus when the printing apparatus is selected by the selection operation, and executes a second transmission process of sending the data to the storage using storage location information associated in advance with the storage when the storage is selected by the selection operation.

A printing system that performs printing includes a printing apparatus in which at least a part thereof is configured by a unit part which is a replaceable function component. The printing apparatus is controlled using a command group including a printer control command which is a command for controlling the printing apparatus and a unit inspection command which is a command used for an inspection of the unit part. At least a part of the printing apparatus is configured by a plurality of unit parts having different functions. The plurality of unit parts are configured to be inspected using the unit inspection command.

In a case where a print job not performed according to designation of a first object for performing at least one print job without an authenticated user selecting the at least one print job is included in print jobs stored in association with identification information of the authenticated user, an image processing apparatus displays a second object for displaying a list of the print jobs stored in association with the identification information of the authenticated user in preference to the first object on a screen displayed on an operation device after the authentication.

A controller of an information processing apparatus is configured to receive image data representing a first size image, the first size being a size within which a first number of first objects can be printed, extract second image data included in the first image data, the second image data representing the first object, create first print data used to print the second number of first objects on the second size sheet in an arranged manner based on the extracted second image data, the second number being less than the first number, the first size being a size of a sheet on which the first number of first objects can be arranged, the second size being a size of a sheet on which the first number of first objects cannot be arranged but the second number of first objects can be arranged, the first print data being transmitted to a printer.

A display control device according to an embodiment includes a display control unit that controls display of a setup screen for performing setup for machining in a machine tool, the setup screen including (i) a menu display part displaying a plurality of setup items in a selectable manner and (ii) a detail display part displaying an operation for each of the setup items. In control of display of the setup screen, while the setup screen is displayed, display of the setup items on the menu display part is maintained and display of the operation screens is switched on the detail display part in response to an operation input by an operator.

A controller of an information processing apparatus is configured to receive image data representing a first size image, the first size being a size within which a first number of first objects can be printed, extract second image data included in the first image data, the second image data representing the first object, create first print data used to print the second number of first objects on the second size sheet in an arranged manner based on the extracted second image data, the second number being less than the first number, the first size being a size of a sheet on which the first number of first objects can be arranged, the second size being a size of a sheet on which the first number of first objects cannot be arranged but the second number of first objects can be arranged, the first print data being transmitted to a printer.

A method for processing print data includes a matching processing step of performing pattern matching between a streak detection pattern including a streak pattern having a width of one pixel and print data after a RIP process, a length measurement step of determining, when matching is established in the matching processing step, a length of a streak candidate part including a part corresponding to the streak pattern in a region where matching is established and a part continuous in an extending direction of the streak pattern and having a same value as a data value of the streak pattern, in the print data, and a determination step of determining whether or not the streak candidate part is white streak data that possibly results in a streak, by comparing the length determined in the length measurement step against a predetermined threshold.
