Abstract

PURPOSE:To prevent the shift of a printing position and the lowering in printing grade, by providing a function for performing printing in such a state that one printing block is divided plural times and a function for fixing paper in a non-movable state before the finish of split printing. CONSTITUTION:For example, when two characters of 'XA' are set as one block to perform two-split printing, first printing 3 is performed and a printing position is returned to the original position during a period 1. to perform second printing. In a conventional system, since paper is fixed only for periods 7., 8., the paper moves at a point 2 for the period 1. and a printing result generating the shift of characters is brought about. Therefore, in this system, the paper is fixed even during a period returning the printing position. That is, when printing is performed in such a state that one block is split plural times, the paper is fixed before split printing is finished to bring about effect for capable of preventing the lowering in printing grade by preventing paper shift.

中身外はプラテンを７！Ｊ−Ｋしていた。Conventionally, this type of serial printer divides one block into multiple prints due to the lack of printing performance and low noise. , physical characteristics of the head and ribbon). Conventional printers (especially those that use ribbons) also have a function to prevent the platen from being moved during printing, and to further reduce power consumption, the platen is moved 7 times when not printing. I was doing J-K.

When the paper is fixed again (point indicated by 2), the precision of the platen feed motor is affected, resulting in misalignment of the printing position and deterioration of printing quality.

In this example, two characters of ``@n'' are used as one block and two-part printing is performed.The first printing prints λ, and in the 1.0 period, the printing position is returned to the original position and the book is printed. There is.
