A printing apparatus includes a head to discharge liquid, a carriage to support the head and reciprocate in a forward direction and a backward direction, and a controller. The controller executes a printing process to print one image in a plurality of copies by discharging the liquid from the head while moving the carriage in the forward direction and the backward direction, based on a print job for printing the one image in the plurality of copies, and a first determining process to determine a moving direction of the carriage for second and following copies, based on a moving result of the carriage in printing for the first copy in the printing process.

Various embodiments illustrated herein disclose a method comprising rendering a buffer image from a first image data received for printing. Further, the method includes scaling the buffer image to generated scaled buffer image. Furthermore, the method includes determining a first location of a machine readable indicia in the scaled buffer image. Additionally, the method includes causing a print head to print the buffer image on a print media to generate a printed content.

A non-transitory computer-readable recording medium for an information processing apparatus contains instructions which cause, when executed by a controller, the information processing apparatus to perform identifying a sheet size of a sheet which is used for printing based on identifying data, the identifying data being received through the input interface and identifying the sheet size based on the received identifying data, receiving image data which is output by the application, when the received image data represents an image in which a first object is arranged, when the size of the image is a first size, and when the identified sheet size is a second size, extracting object image data representing the first object from the image data received in the receiving process, generating printing data, and outputting the generated printing data to be transmitted to the printer through the communication interface.

Examples described herein relate to a system consistent with the disclosure. For instance, the system may comprise a printing device including hardware to form markings on a print medium, a memory resource, and a controller to receive a print job to form the markings on the print medium, render a page description language of the print job to form the markings, determine an object type image of the print job, designate pixels of the determined object type image to form a covert dot pattern on the image, and adjust colors of the designated pixels to form the covert dot pattern on the markings.

Various embodiments illustrated herein disclose a method comprising rendering a buffer image from a first image data received for printing. Further, the method includes scaling the buffer image to generated scaled buffer image. Furthermore, the method includes determining a first location of a machine readable indicia in the scaled buffer image. Additionally, the method includes causing a print head to print the buffer image on a print media to generate a printed content.

One embodiment comprises a print controller that stores a first print job comprising print data objects and print job commands, processes the print job commands to identify the print data objects for the first print job, selects a subset of the print data objects for processing, and encrypts the subset of the print data objects using a key while the print data objects not selected for processing and the print job commands remain unencrypted, identifies outlines and presentation positions specified for the subset of the print data objects, and generates one or more auxiliary print data objects that graphically represent the outlines and the presentation positions of the subset of the print data objects. The print controller generates a second print job comprising the encrypted print data objects, the auxiliary print data objects, the unencrypted print data objects, and unencrypted print job commands, and provides the second print job.

Print jobs may include errors, which may be difficult to resolve. In the embodiments described herein, data objects in print jobs are converted into printable features that show the underlying information in the print job, which allows for a visual inspection of the logical structures and relationships between the logical structures and print data objects in a printed output. One embodiment comprises a print controller that stores a first print job comprising one or more data objects, and print job commands that define the data objects for the first print job. The print controller processes the print job commands to identify the data objects for the first print job, and outlines and presentation positions specified for the data objects, and generates a second print job that graphically represents the outlines and the presentation positions of the data objects as graphical shapes, and provides the second print job.

An apparatus configured to generate image data represented in achromatic color from input image data and output the generated image data to a printer includes a controller. The controller is configured to replace color information of an object included in the input image data with an achromatic signal value, determine, based on an achromatic signal value corresponding to color information of a pixel of interest in the input image data, whether the pixel of interest satisfies a predetermined condition, and perform enhancement processing on the color information of the pixel of interest in a case where the pixel of interest is determined not to satisfy the predetermined condition.

A printing apparatus includes a pattern extracting unit for, based on a comparison between first image data representing a pattern and second image data generated by imaging a fabric transported, extracting a pattern region from the second image data, a printing image generation unit for arranging third image data representing an image to be printed overlaid on the pattern so that the third image data matches the pattern region to generate printing image data, and a printing control unit for causing a printing unit to print the printing image data on the fabric transported.

A printing apparatus includes: a head which discharges liquid to a medium; and a controller. The controller obtains print data for forming an image on the medium with a dot formed by making the liquid to land on the medium, the image including a code having information; selects, in the obtained print data, dot data corresponding to the dot forming the image as selected data, determines whether a first dot pattern including the selected dot data matches a predetermined delete pattern, and determines whether a second dot pattern including the selected dot data matches a predetermined exclusion pattern; performs a correction of the print data based on results of the determinations; and discharges the liquid from the head to the medium, based on the print data after the correction, to form the image on the medium.
