Abstract: Traditionally, in the case in which an image is projected onto an object of projection not equipped with frame marking edges, markers have had to be attached to the object of projection each time in order to automatically adjust the size of the projection region to which the image light is projected, which was cumbersome. Thus, in the present invention, in projecting the test pattern images onto the object of projection, the zoom projection lens is adjusted to enlarge the size of the projection region gradually, and the projection region is imaged each time. After the vertex of the object of projection matches the edge of the object of projection, when the projection region becomes forced out from the area of the object of projection, a part of the contour of the test pattern images projected within the imaged image matches a part of the edges of the object of projection. Therefore, the contours of the test pattern images projected within the projected images are compared before and after the enlargement.

Abstract: A printing apparatus has a printing head which gradually prints a print image on an object to be printed, and a display which visibly displays the non-printed portion which gradually decreases with the progress of the printing work of the print image. A printing system has a data server which feeds the print image data through an interface capable of transmitting the print image data, and a printing apparatus which receives the print image data through the data server and gradually prints the print image on the object to be printed based on the print image data. The data server visibly displays the image of the non-printed portion which gradually decreases with the progress of the printing work of the print image.

Abstract: A tape made up of a base tape having a front printing surface and a rear adhesive surface, and a release tape covering the adhesive surface is mounted on a printing apparatus. A plurality of print images are printed on the printing surface in a manner arrayed in a longitudinal direction of the printing tape, and the printing tape is cut in the widthwise direction thereof. Connection cutting is performed such that at least a widthwise part of the release tape remains connected as a connection portion in a space between respective adjoining print images.

Abstract: There is provided an method for a character-outputting apparatus which is capable of storing a character image defined by a character font, as bitmap data in the form of a dot matrix, and printing or displaying the character image. The bitmap data is converted temporarily to vector data when the character image is enlarged. Then a new line is drawn from a starting point of each vector of the vector data to an ending point of the vector in a vector direction, where is included a diagonal discontinuity between dots diagonally adjacent to each other, and an inside of the new line is filled to thereby regenerate bitmap data corresponding to the character image.
