Problems solved by technology

[0005] However, depending on the accuracy of the motor that is the driving source of the moving mechanism, the speed of the sub-scan becomes uneven when the speed of the sub-scan is stabilized to a certain speed.
Moreover, due to the unevenness of the speed, the image quality of the printed area may deteriorate during this period.

Embodiment Construction

[0046] Hereinafter, an embodiment will be described with reference to the drawings.

[0047] figure 1 It is a diagram showing the configuration of a part of the mechanism and the block configuration of main circuits of the printer according to the present embodiment. In addition, in this embodiment, a thermal printer is taken as an example for description.

[0048] Such as figure 1 As shown, the printer 100 includes a thermal print head 1 , a stepping motor 2 , a conveying mechanism 3 , a cutter unit 4 , a motor driver 5 , a drive control unit 6 , a print control unit 7 , a memory 8 and a bus 9 .

[0049] The thermal print head 1 is a type of print head, and prints an arbitrary image on the print medium 200 by discoloring the print medium 200 through heat generated by each of a plurality of heating elements. The thermal print head 1 can individually and multi-stagely change the heating temperature of each of the plurality of heating elements, and can print multi-level grays...

Abstract

The invention discloses a printer, a control method, and a terminal device, which can print images without degrading the image quality during the period from the start of the sub-scanning to the stabilization of the speed of the sub-scanning. The printer includes: a printing head, a moving mechanism, a printing control department and mobile control department. The moving mechanism includes a stepping motor, and moves at least one of the printing medium and the printing head so as to change the relative positions of the printing medium and the printing head. The printing control unit activates the moving mechanism according to the printing start instruction, and controls the printing head so that the printing corresponding to one raster is performed every time the relative position between the printing medium and the printing head is changed by the moving mechanism according to the interval of the raster. The movement control unit controls the movement mechanism so that the driving interval of the stepping motor is longer than the previous interval at least once before the rotation speed of the stepping motor reaches a predetermined target speed after the movement mechanism is activated.

Description

[0001] This application claims that the Japanese application with the filing date of July 21, 2017 and the application number of JP2017-142014 is the priority, and cites the content of the above application, and its disclosure content is incorporated herein by reference. technical field [0002] Embodiments of the present invention relate to a printer, a control method, and a terminal device. Background technique [0003] Conventionally, there is known a printer that prints a two-dimensional image while sub-scanning by moving at least one of the print medium and the print head by a moving mechanism, using a print head that prints a part of a plurality of rasters constituting an image at a time. [0004] In such a printer, in order to prevent a blank from being generated on the leading side in the sub-scanning direction of the printing medium, it is desirable to have a technology that enables image printing to be started simultaneously with the start of sub-scanning. [0005]...
