An information processing apparatus that manages print processes of plural printing apparatuses, the information processing apparatus includes a processor configured to acquire execution information indicating an execution status of each printing apparatus from the plural printing apparatuses, in a case in which a predetermined condition regarding processing of converting print data into a raster image is satisfied in one printing apparatus, extract another printing apparatus capable of executing the processing of converting the print data into the raster image from among other printing apparatuses other than the one printing apparatus by using the execution information, cause the other printing apparatus, that is extracted, to execute the processing of converting the print data of a print job scheduled to be printed in the one printing apparatus into the raster image, and perform control to transmit the raster image created by the other printing apparatus to the one printing apparatus.

A tape printing apparatus includes an input unit for performing editing, a temporary storage unit configured to temporarily store editing information being edited by the tape printing apparatus, and an editing-information transmitting unit configured to transmit the editing information to a portable terminal when a first operation button included in the input unit is operated in a state in which the editing information is stored in the temporary storage unit.

A print control device is provided with a storage unit that stores print data which is being processed in another print control device that controls a printing device so as to perform print processing based on received print data, an acquisition unit that acquires second printed-page information from the printing device, and a controller. When an error occurs in the other print control device, the controller receives first printed-page information from the other print control device, determines a restart page from the first printed-page information received from the other print control device and the second printed-page information acquired by the acquisition unit, and controls the printing device on behalf of the other print control device so as to restart the print processing based on the print data from the restart page.

A method of compositing layers by grouping the layers into a foreground group and a background group; identifying independent instructions of compositing model for execution independently from the background group and dependent instructions requiring a compositing output of a background layer in order to composite foreground layers; executing the independent instructions on the foreground layers in parallel with compositing the background layers, a first independent instruction storing a corresponding result in a first buffer and a second independent instruction storing a corresponding result in a second buffer; executing a dependent instruction by updating the second buffer using the background compositing output; and determining a compositing output for the foreground group dependent upon contents of the first buffer and the updated second buffer.

An information processing apparatus prints, when a first product is read by a reading apparatus, a first work instruction sheet including information about all products to be delivered to a first destination of the read first product, prints, if all products to be delivered to the first destination are read by the reading apparatus, a first shipping label for delivery to the first destination, determines, if a second product to be delivered to a second destination different from the first destination is read by the reading apparatus, whether any other product is to be delivered to the second destination, and prints, if it is determined that there no other product is to be delivered to the second destination, a second shipping label for delivery to the second destination.

An image processing method configured to process an image constituted by a plurality of pixels arranged two-dimensionally includes the steps of dividing the image into a plurality of blocks, and comparing image data of the pixel included in a first block as one of the blocks divided into with a first threshold value, and converting the image data into first dot data representing whether to form a dot using an error diffusion method. Further, processing of comparing image data of the pixel included in a second block as a block adjacent to the first block with a second threshold value prepared in advance, and converting the image data into second dot data representing whether to form a dot using an error diffusion method is performed independently of a first processing section. On this occasion, the first threshold value and the second threshold value include variable components periodically varying along two-dimensional arrangement directions of the pixels, respectively, and the variable components are provided with the same phase at a junction between the first block and the second block.

A display apparatus include: a displayer that displays on a screen at least one image used for an operation to instruct execution of processing under a predetermined condition; a preparation detector that detects preparation performed by a user for the processing; and a disabling unit that disables a non-target image used for an operation to instruct execution of non-target processing different from target processing corresponding to a result of detection of the preparation detector, the non-target image being of the at least one image displayed on the screen.

In a case of a first function of carrying out a cooperative processing in accordance with an instruction from a user of a multifunction peripheral (10), the user is set as an execution user. In a case of a second function of carrying out a cooperative processing in accordance with an instruction from an application, a user instructed by the application is set as an execution user. Further, in a case where an execution user of a cooperative processing carried out using the first function and an execution user of a cooperative processing carried out using the second function are identical, use history information of the execution user is managed as use history information of a single user. This makes it possible to appropriately manage use history information of a cooperative processing.
