Dynamic pattern transfer printing systems and method are provided, which decouple the design of the trench patterns on a source substrate for pattern transfer printing, from the resulting metallic paste lines patterns transferred to a receiving substrate, such as PV cells. The receiving substrate may be moved forward (along the scanning direction of the laser illumination used to transfer the paste from the trenches onto the receiving substrate) to reduce the pattern pitch with respect to the source substrate, and/or the receiving substrate may be moved backward (against the scanning direction) to increase the pattern pitch with respect to the source substrate. For example, dynamic pattern transfer printing may be used to accommodate different widths of the substrates for more effective pattern transfer, and/or to enable one-to-many pattern transfer technologies with high wafer throughput. Also, pattern transfer sheet with separate multiple groups of trenches are provided.

There is provided a laser apparatus for a printed electronic system according to an exemplary embodiment of the present invention including: a laser generating unit which oscillates a laser beam; a laser changing unit which changes an intensity or a wavelength of the laser beam oscillated from the laser generating unit; a laser control unit which controls the intensity or a magnitude of the wavelength of the laser beam which is changed by the laser changing unit; and a laser steering unit which changes a traveling direction of the laser beam output from the laser changing unit to be directed to a target, and the laser control unit controls the intensity or the magnitude of the wavelength of the laser beam in accordance with a state of a printing pattern formed on the target.

The invention relates to an inkless printing method. The invention also relates to an inkless printing device, in particular configured to perform at least a part of the method according to the invention. The invention furthermore relates to a substrate provided with at least one printed marking realised by applying the method according to the invention and/or the device according to the invention.

According to one embodiment, the label printer includes a light irradiation unit that irradiates an area illuminated by external light where a label on which printing is completed exists with light, a light irradiation control unit that switches between light irradiation and non-irradiation by the light irradiation unit, a light receiving unit that acquires an optical signal from the area where the label on which printing is completed exists in synchronization with the light irradiation and non-irradiation by the light irradiation control unit, and a label presence or absence determination unit that determines the presence or absence of a label based on a first signal acquired by the light-receiving unit if the light irradiation unit is not emitting light and a second signal acquired by the light receiving unit if the light irradiation unit is emitting light.

A laser printhead assembly for a laser printhead is disclosed herein. The laser printhead assembly may include a laser containment door; and a laser containment housing that is configured to form a sealed enclosure with a label support of a rewriteable label. The sealed enclosure may be configured to include the rewriteable label and the laser printhead. The laser containment door, in a laser-enabled position, may be configured to permit the laser printhead, via a light beam, to modify the rewriteable label and the laser containment door, in a laser-disabled position, may be configured to prevent a light beam from escaping the laser containment housing.

To improve convenience in use of a laser marking apparatus that performs marking on a workpiece to which an alignment mark is affixed. The laser marking apparatus includes a setting section, a second IF section, a movement amount monitoring section, and a marking control section, and the setting section causes a display section to display a setting-assist image, which visually indicates the alignment mark on the flexible workpiece and a trigger delay, and receives a user input for setting the trigger delay in a state where the setting-assist image is displayed.

An optical scanning unit includes a rotatable multi-faceted mirror having a plurality of faces reflecting light flux emitted from a light source to scan a scanning area in a main scanning direction. A width of the light flux striking the rotatable multi-faceted mirror is smaller than a length of a face of the rotatable multi-faceted mirror. The entire of light flux striking the rotatable multi-faceted mirror is reflected at a first face when the light flux reflected by the rotatable multi-faceted mirror is directed to the center portion of the scanning area. A part of the light flux striking the rotatable multi-faceted mirror is reflected at the first face while the remaining of the light flux is reflected at a second face when the light flux reflected by the rotatable multi-faceted mirror is directed to a least one of the two end portions of the scanning area.
