According to one embodiment, a printer includes a motor and a roller turned by the motor to discharge a backing sheet-attached label from a roll wound with the backing sheet-attached label, or a liner-less label from a roll wound with the liner-less label with an adhesive surface on one side of the liner-less label. The printer further includes a print unit to perform printing on the backing sheet-attached label or the liner-less label discharged from the roll, a switching unit to switch the printer to a standard mode in which the print unit performs printing on the backing sheet-attached label or a liner-less mode in which the print unit performs printing on the liner-less label, and a control unit to control the operation of the motor in response to the switching of the printer to the standard mode or the liner-less mode.

Printer and method for switching between standard mode and liner-less mode

A thermal printing apparatus includes a thermal head having a plurality of heating elements arranged in a line. The thermal printing apparatus may further includes a control unit configured to determine conduction times of the heating elements based on print rates respectively assigned to the plurality of heating elements. The control unit may be further configured to compensate each of the determined conduction times based on the conduction times of the heating elements other than the respective heating element to determine a plurality of compensated conduction times. The control unit may control each of the plurality of heating elements based on the respective one of the plurality of compensated conduction times to enable the thermal head to perform printing on a recording medium.

Thermal printing apparatus and control method thereof

A thermal transfer type color printer of this invention has four ink ribbons sequentially arranged from a first order to a fourth order along a conveying direction of a printing medium, and four printing heads respectively arranged in accordance with the four ink ribbons. Each of the printing heads melts and transfers ink included in each of the ink ribbons to the printing medium by heating the ink ribbons while each of the ink ribbons comes in contact with the printing medium. While the printing medium is conveyed, the ink of each of the ink ribbons is transferred to the printing medium so that a color image is formed. In this color printer, a melting viscosity of the ink of an ink ribbon used at a later stage is set to be lower than that used at a previous stage.

Thermal transfer type color printer

A color printer includes a plurality of platens arranged on paper feeding path to feed paper on which a plurality of printing areas are arranged in series, a plurality of print heads arranged on the feeding path to face the platens to print data on the same printing areas of the paper fed on the feeding path, a feeding roller for feeding, to the print heads, the paper along the feeding path, a front-edge sensing section disposed between the feeding roller and a print head nearest the feeding roller to detect that the paper has been positioned at a printing start position, and a plurality of head lift mechanisms for setting the print heads from the platens to a standby position apart from the platens before the paper is fed to the printing start position and to a contact position at which the print heads come in contact with the platens after the paper has been fed to the printing start position. Particularly, the color printer has an engine controller for sequentially driving the head lift mechanisms to set the print heads to the contact position when the front edge of the paper has reached positions slightly advanced over the print heads.

Printer device

A deviation test pattern includes a reference scale printed by one reference printing unit among a plurality of printing units arranged to print overlaid images of yellow, magenta, cyan and black. The reference scale has a plurality of scale bars arranged in a main-scanning direction at a pitch of 30 dots. Particularly, the deviation test pattern further includes a difference scale printed adjacent to and in parallel to the reference scale by a printing unit other than the reference printing unit. The difference scale has a plurality of scale bars arranged in the main-scanning direction at a pitch of 29 dots (or 31 dots).

Printer device and method for printing deviation test patterns to

Of a plurality of page memories for storing printing data corresponding to the printing heads, at least the page memory is associated with an auxiliary memory for storing at least two continuous pages of printing data for at least one printing head, wherein a printing data write unit executes a process for writing the next page of printing data in one of the page memory and the auxiliary memory while the printing data stored in the other one of the page memory and the auxiliary memory is being printed, and the image processing unit supplies printing data continuously and alternately from the page memory and the auxiliary memory to each corresponding printing head.

Color printer

Disclosed herein is an image printing method whereby a line head of a line printer performs line emission a plurality of times to print one primary scanning line. The number of times light is emitted by each edge emission type EL device corresponding to each pixel of one primary scanning line is controlled according to print density information contained in an input print signal. A plurality of flat pixel components are generated lengthwise and crosswise to form an approximately square pixel. This pixel is printed a plurality of times lengthwise and crosswise to form an image. The edges of the image are filled with suitably positioned pixels that have some of their components selectively left blank for visually smoothing effects.

Image printing method for edge emission type EL printer

An edge emission type EL printer having a line head constituted by an array of numerous edge emission type EL devices. One group of electrodes for the EL devices receive driving pulses from a first driver means, and the other group thereof get driving pulses from a second driver means as per emission control signals. This allows the EL devices to selectively luminesce, forming an electrostatic latent image on the circumference surface of a photosensitive body charged by a charger. The image is developed by a developer and transferred to a recording medium by a transfer machine. The emission control signals entering the line head are monitored so that when the absence of EL devices luminescing within one primary scanning line is detected from the monitoring, a driving pulse stopping means is activated to stop accordingly the driving pulses continuously applied to the EL devices by the first driver means.
