본 발명은 프린터의 프린팅방법에 관한 것으로서, 특히 프린트가 기록지에 화상을 인쇄할 때. 기록지에 상하단여백이 없이 인쇄하는 여백이 없는 프린터의 인쇄방법에 관한 것이다.BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a printing method of a printer, particularly when a print prints an image on a recording sheet. The present invention relates to a printing method of a printer having no margin printed on a recording sheet without top and bottom margins.

화상데이타를 프린터로 기록지 위에 인쇄하는 방식은 열러 가지가 있다. 예를 들어, 화상데이타를 열로 변환시키는 열전사헤드와 열전사헤드 하부에 있는 잉크필름을 사용하여 잉크필름 하부에 위치한 기록지에 인쇄하는 방법이 있다. 칼라형 열전사프린터는 풀 칼라(full color)를 실현하기 위하여 색 분해된 옐로우, 마젠타, 시안의 분해 화상을 3번에 걸쳐 중복 인쇄되는 형태를 갖는다.There are several ways to print image data on a recording sheet with a printer. For example, there is a method of printing on a recording sheet located below the ink film using a thermal transfer head for converting image data into heat and an ink film under the thermal transfer head. The color thermal transfer printer has a form of overprinting three times the decomposition images of color-decomposed yellow, magenta, and cyan in order to realize full color.

칼라로 인쇄된 인쇄물은 사진기로써 찍은 필름을 인화지에 인화했을 때만큼이나 선명하여, 스캐너와 같은 화상 입력장치로서 영상을 입력하여 컴퓨터 프로그램을 이용하여 상기 입력된 화상을 수정 및 합성하여 새로운 화상을 구성하여 다시 사진으로 출력하거나, 컴퓨터 그래픽으로 가상의 실물을 재현한다던가, 의료 기기의 엑스레이(x-ray)필름과 단층 촬영된 영상을 칼라로되 오에이치피(Over Head Project)필름화 하는데 사용된다. 근래에는 사진의 대용으로 많이 사용하려고 하고 있으며, 따라서 사진과 같은 화질과 형태가 요구된다.The printed matter printed in color is as sharp as when the film taken by the camera is printed on photo paper, and the image is input using an image input device such as a scanner, and the new image is formed by modifying and combining the input image using a computer program. They can be used to print out photographs, reproduce virtual reality with computer graphics, or to produce x-ray and tomographic images of medical devices in color and over head projects. In recent years, it is trying to use a lot as a substitute for a picture, and therefore, the same picture quality and form are required.

제1도는 종래의 실제 화상 인쇄범위를 도시한 도면이다. 도시된 바와 같이, 기록지에 인쇄되는 실제 화상(1)이 기록지에 상하 여백(2)을 가진 체로 인쇄되었다. 이와 같이 기록지에 여백이 남을 수밖에 없는 이유를 살펴보면 다음과 같다.1 is a diagram showing a conventional actual image printing range. As shown, the actual image 1 printed on the recording paper was printed on the recording paper in a sieve having upper and lower margins 2. The reason why there is no space left on the sheet is as follows.

제2도, 제3도, 제4도는 종래의 인쇄방법을 설명한 드럼방식프린터, 프레턴방식프린터, 캡스턴롤울러방식프린터의 각각의 측면도이다. 도시된 바와 같이, 제2도의 드럼형 프린터의 경우 기록지(3)를 팽팽하게 함과 동시에 드럼(4)에 밀착시키기 위한 클램핑기구(5)를 사용하였다. 따라서, 클램핑기구(5)에 의하여 기록지가 드럼(4)에 밀착된 기록지의 선단은 프린트할 수 없었다. 제3도의 플래턴방식의 경우에도 가이드로울러(8)가 드럼 (4)과 함께 물고 있는 기록지(3)의 선단부터 인쇄헤드(10)까지의 기록지는 인쇄되기가 어려웠다. 그리고, 제4도에 도시된 바와 같이, 캡스턴롤러 방식의 프린터기에 있어서도 마찬가지로 기록지(3)를 팽팽해가 하는 제2캡스턴롤러(16)부터 인쇄헤드(10)까지의 기록지(3)는 여백으로 남고, 이 인쇄헤드(10)부터 제1캡스턴롤러(14)까지의 기록지(3)의 뒷부분도 여백으로 남는다.2, 3, and 4 are side views of a drum printer, a preton printer, and a capstan roller roller printer, each of which describes a conventional printing method. As shown, in the case of the drum type printer of FIG. 2, a clamping mechanism 5 was used to make the recording paper 3 taut and close to the drum 4. Therefore, the tip of the recording paper in which the recording paper was in close contact with the drum 4 by the clamping mechanism 5 could not be printed. Even in the case of the platen method of FIG. 3, it is difficult to print the recording paper from the tip of the recording paper 3 to which the guide roller 8 is held together with the drum 4 to the print head 10. FIG. As shown in FIG. 4, the recording paper 3 from the second capstan roller 16, to which the recording paper 3 is tensioned, to the print head 10 is similarly spaced in the capstan roller type printer. The remaining portion of the recording sheet 3 from the printhead 10 to the first capstan roller 14 is also left blank.

상술한 여백은 미관상 좋지 못할 뿐만 아니라 기록지가 낭비되고, 스캐너 상으로 입력된 화상이 이렇나 방식의 프린터로 인쇄할 경우 상하에 인쇄될 화상이 상술한 이유로 인하여 축소 인쇄되거나 화상이 절단될 수밖에 없다.The above-mentioned margins are not only aesthetically unfavorable, but the recording paper is wasted, and when the image inputted on the scanner is printed with a printer of this type, the image to be printed on top and bottom is reduced or printed due to the above-mentioned reasons.

따라서 본 발명의 목적은 왼쇄물의 여백을 제거하여, 기록지의 낭비와 화상의 축소와 절단을 방지할 뿐만 아니라, 미관상 사진과 같은 여백이 없는 인쇄물을 제공하기 위한 프린터의 인쇄방법을 제공하는데 있다.Accordingly, it is an object of the present invention to provide a printing method of a printer for removing waste of left printed matter, preventing waste of recording paper and reducing and cutting of images, as well as providing prints without margins such as aesthetic images.
