Provided is a printing apparatus in which: a platen includes a plurality of contact portions configured to be brought into contact with a printing medium to support the printing medium, and a plurality of non-contact portions configured not to be brought into contact with the printing medium; the plurality of contact portions are disposed at positions differing from each other in a transport direction, and are each provided between the non-contact portions; and when performing marginless printing for discharging ink to an end portion, in the transport direction, of the printing medium, a control unit changes an area of a nozzle used in the marginless printing to any of a plurality of nozzle areas corresponding respectively to the plurality of non-contact portions in the transport direction, in accordance with deposit information indicating the amount of deposits of the ink at the non-contact portions.

An ejection apparatus includes a platen for supporting a recording medium, an absorber provided in the platen for absorbing liquid, an ejection unit for ejecting a plurality of types of ink including a first liquid containing a component to be deposited when the first liquid is ejected onto the absorber, and a second liquid different from the first liquid for suppressing deposition of the first liquid, a detection unit for detecting a state of a predetermined region of the absorber, and a control unit for controlling the detection unit to detect the state, and controlling the ejection unit to eject the second liquid to the predetermined region based on a result of the detection. When the first liquid is ejected to the predetermined region, the second liquid is ejected to the predetermined region after the ejection of the first liquid is finished, without using the result of the detection.

A printing apparatus includes a conveyance unit to convey a printing sheet in a conveyance direction, a printing unit to print on the conveyed printing sheet, a print unit, and a carriage to move in a direction crossing the conveyance direction. A detection unit detects a sheet edge of the print sheet based on output from a light receiving unit, and a control unit controls a borderless printing by the print unit that includes an extra-printing from the sheet edge to outside of the sheet. When the control unit performs the borderless printing, the control unit obtains an instruction to perform the borderless printing, and then causes the light receiving unit to obtain the output by causing the light emitting unit to emit the light, and thereafter the control unit sets an extra-printing amount by which printing extends off the sheet edge based on the obtained output.

A handheld printing device includes a printing mechanism and a light source. The printing mechanism prints a swath of print material onto a print medium as the handheld printing device is moved across the print medium. The light source projects onto the print medium a light box. The light box has top and bottom edges corresponding to the swath and indicating where the printing mechanism will print the swath as the handheld printing device is moved across the print medium.

A printer comprises at least one longitudinal cutter module to cut a print medium in a longitudinal direction with respect to a print media advance direction. The printer comprises a controller to position the longitudinal cutter module along a direction perpendicular to the print media advance direction. The controller is to receive a full-bleed print job and in response to receive print job to position the at least one cutter module along the direction perpendicular to the print media advance direction. The longitudinal cutter module is positioned by the controller to longitudinally cut the print medium.

Techniques for handling and reducing ink overspray of an ink jet printer are provided. In an example, an ink overspray collector for an ink jet printer can include a first opening defining a first print area of the ink jet printer, and a frame about the first opening. The frame is configured to receive overspray from operation of the ink jet printer and can be formed of a woven material. In some examples, a controller of the ink jet printer can reduce an amount of ink ejected near the edges of the print media to reduce overspray.

A printing apparatus includes an image processing unit and generates a product by performing printing on a print medium conveyed in a conveyance direction intersecting a width direction, based on data for printing, and then cutting a width-direction end portion of a printed image, wherein the image processing unit calculates a first ink application amount of a first area formed at one end portion in the width direction on a leading edge side of the image which is located on a downstream side in the conveyance direction during printing and a second ink application amount of a second area formed at the other end in the width direction on the leading edge and enlarges the image data at a predetermined ratio to obtain the data for printing in a case where at least one of the first ink application amount and the second ink application amount exceeds a threshold value.

A printer comprises at least one longitudinal cutter module to cut a print medium in a longitudinal direction with respect to a print media advance direction. The printer comprises a controller to position the longitudinal cutter module along a direction perpendicular to the print media advance direction. The controller is to receive a full-bleed print job and in response to receive print job to position the at least one cutter module along the direction perpendicular to the print media advance direction. The longitudinal cutter module is positioned by the controller to longitudinally cut the print medium.

Devices and methods for identifying border positions of print media in image forming apparatuses are disclosed. In an example method print media are advanced in a feeding direction to reach a cutting position, a cutter is advanced in a cutting direction, perpendicular to the feeding direction to cut the print media, changes in friction are identified when the cutter contacts the print media, positions of the cutter are identified when the changes in friction are identified and border positions are determined based on the identifying of cutter positions.

A printing method includes printing an image on a sheet with a printhead, detecting an edge of the printed image in a widthwise direction of the sheet, and performing borderless printing, based on the detection result, to make a margin amount in the widthwise direction become not more than a predetermined value so as to prevent the image from being formed outside of the sheet in the widthwise direction.
