Thermal printing systems are described. The thermal printing systems and methods described provide efficient, compact, and fast thermal printing by providing preheating components that generate a priming thermal energy which preheats thermal paper in the printing system. The priming thermal energy decreases the amount of energy needed to activate the thermal paper during printing. The system and methods also include an optical print head which activates thermal paper using optical energy, which provides for multiple different types of efficient component configuration and increased speed of printing.

A method for writing an imageable material using multiple beams includes preparing subsequent patterns each having Y rows of N pixel locations, said subsequent patterns including first and second patterns; where the first and the second pattern overlap with each other in an overlap area consisting of O columns and Y rows of pixel locations; selecting for each row i of said first pattern Mi1 pixel locations; selecting for each row i of said second pattern Mi2 pixel locations; writing simultaneously, for each row i, said Mi1 selected pixel locations by moving the N beams in a fast scan direction relative to said imageable material; and moving said N beams relative to said imageable material in a slow scan direction over (N-O) pixel locations; writing simultaneously, for each row i, said Mi2 selected pixel locations by moving the N beams in a fast scan direction relative to said imageable material.

Provided are a personalized automatic customization method and an apparatus for a ring-pull can. In the apparatus, a bin device is located at an upper part of the apparatus, a distributing device is installed below a bin device, and a pushing device is arranged on a side of the distributing device and a positioning device. A pattern of a marking content is set on the control system, and a feeding wheel is driven to rotate so that a canned beverage falls down. The pushing device pushes the ring-pull can to the positioning device. The control system receives the positioning signal, and a marking header of the marking device is driven to mark on an outer surface of the ring-pull can. The pushing device pushes the ring-pull can towards a second chute, and an electrical thrust cylinder extends the electric push rod out thereof to push the discharging hopper forward.

Optical scanner and electrophotographic image forming device are provided. The optical scanner includes a light source; and a first optical unit, a deflection apparatus, and an f-θ lens, which are sequentially arranged along a primary optical axis direction of a light beam emitted from the light source. The light beam emitted from the light source is focused onto a scanning target surface after sequentially passing through the first optical unit, the deflection apparatus, and the f-θ lens. Optical scanning directions of the light beam emitted from the light source include a primary scanning direction and a secondary scanning direction which are perpendicular to each other, and along the primary scanning direction, the f-θ lens satisfies following expressions: SAG1>0, SAG2>0, and 0<(SAG1+SAG2)/d<0.8.

Provided is an articulated robot arm capable of laser printing. The articulated robot arm includes: a communicator for receiving beverage order information; a grip part gripping and moving a cup; an articulation part having one side coupled to the grip part and including a plurality of articulation units; a controller controlling operations of the grip part and the articulation part; and a laser beam irradiation unit provided on at least a partial area of the grip part and irradiating a laser beam to print the beverage order information on the cup.

A laser recording method is for processing a recording object with laser light emitted from a laser light source. The laser recording method includes: detecting a moving speed of the recording object with a location of the laser light source when the laser light source emits laser light, as an observation point, while moving at least one of the recording object and the laser light source; and correcting power output of the laser light set such that an amount of energy applied by the laser light per unit area of the recording object is constant even if the moving speed is changed, to compensate energy loss derived from thermal diffusion occurring on the recording object based on the moving speed detected at the detecting.
