Description

本発明は、印刷装置、制御方法及びプログラムに関するものである。

The present invention relates to a printing device, a control method, and a program .

Claims

A printing device for printing on a recording medium while moving,
A control unit,
A head unit that performs printing based on the input print data,
An image acquisition unit that acquires an image of the recording medium,
The control unit is
At least one of the first and the second recording media displayed on the recording medium based on the image acquired by the image acquisition unit when the image acquisition unit is moving in the moving direction in which the image acquisition unit is on the front side; Detects lines that extend in the direction
A printing apparatus, wherein a printing area is set along the first direction in an area that does not overlap the line of the recording medium.

The control unit is
The determination process for determining whether the print width set by the print data is within the width of the print area in a second direction orthogonal to the first direction is performed. Printing device.

The control unit is
A detection process of detecting, as the line, a first line and a second line shown along the first direction on the recording medium based on the image;
One printing boundary line and the other printing boundary line of the printing area are set along the first direction so that a margin is provided in the second direction for the first line and the second line. By performing the area setting process for defining the print area,
The printing apparatus according to claim 2, wherein the determination process is performed based on whether or not the print width is between the one print boundary line and the other print boundary line.

The control unit is
When the printing width is within the width of the printing area of the recording medium in the second direction, the first distance between one end of the printing width and the one printing boundary line, and the printing a first comparison process to compare with the other end of the width, and a second distance between said other printing boundary,
A first print width adjustment process for reducing the print width so that the shorter one of the first distance and the second distance is matched with the larger distance in the first comparison process. The printing device according to claim 3.

When the print width is not within the width of the print area of the recording medium in the second direction, the control unit controls one of the one end and the other end of the print width. Secondly, the print width is reduced so that an end portion which is not located between the print boundary line and the other print boundary line is located between the one print boundary line and the other print boundary line. Print width adjustment process,
In the second print width adjustment process, when the one end is not located between the one print boundary and the other print boundary, the second print width adjusting process is performed between the one end and the one print boundary. The printing width is made smaller so that the first distance of the first printing distance becomes equal to the second distance between the other end portion and the other printing boundary line, and the other end portion of the one printing boundary line If not located between said other printing borders, according to claim 4, wherein the second distance is processed to reduce the printing width so as to have the same distance as the first distance Printing device.

Equipped with a movement amount detection unit that detects the movement amount,
The control unit calculates the print size of the print data from the print width, and when the print size is equal to or larger than the set size, the detection result of the movement amount by the movement amount detection unit is set in advance. The printing apparatus according to claim 4 or 5, wherein when a certain moving amount is reached, a process of causing the head unit to start printing the print data on the recording medium with the calculated print size is performed. .

Equipped with a movement amount detection unit that detects the movement amount,
Wherein the control unit, the moving amount of the detection result of the movement amount detection unit even reach the moving amount set in advance, a line of Sen及beauty other side of the image or we hand is not detected In this case, the printing apparatus according to claim 3, wherein the head unit starts printing on the recording medium according to preset print data.

The control unit is
A detection process of detecting, as the line, the other line shown along the first direction on the recording medium based on the image;
Based on the image, when a character string shown along the first direction is detected at one end side of the print width of the recording medium, the first direction based on the character string is detected. One line determination process that determines one line along
Area setting processing for defining the print area by setting one print boundary line and the other print boundary line of the print area so as to provide a margin in the second direction for the one line and the other line And do
The printing apparatus according to claim 2, wherein the determination process is performed based on whether or not the print width is between the one print boundary line and the other print boundary line.

The control unit is
A detection process of detecting, as the line, the other line shown along the first direction on the recording medium based on the image;
One line determination process that determines one line along the first direction based on the one end of the print width;
The other print boundary line of the print area is set so as to provide the margin in the second direction orthogonal to the first direction with respect to the other line, and the one line is printed in one of the print areas. Perform the area setting process that determines the printing area by setting the boundary line,
The printing apparatus according to claim 4 , wherein the determination process is performed based on whether the print width is between the one print boundary line and the other print boundary line .

The printing apparatus according to claim 3, wherein a length of the image acquisition unit in the second direction is larger than a length of the head unit in the second direction.

A method for controlling a printing apparatus, which prints on a recording medium while moving,
When the printing apparatus is moving in a moving direction in which the image acquisition unit is on the front side of the head unit that performs printing based on the input print data, the image acquisition unit acquires an image of the recording medium. Image acquisition step,
On the basis of the image acquired by the image acquisition unit, at least one line shown in the recording medium, which extends in the first direction, is detected, and the line in the area which does not overlap the line of the recording medium is detected. An area setting step of setting a print area along one direction, the control method comprising:

A program for a printing device that prints on a recording medium while moving,
For the control unit of the printing device,
When the printing apparatus is moving in a moving direction in which the image acquisition unit is on the front side of the head unit that performs printing based on the input print data, the image acquisition unit acquires an image of the recording medium. Image acquisition process,
