Abstract

PURPOSE:The ordinary printing is performed when mark signal comes in continououly, while the printing density is increased when the previous signal is the space signal and the succeeding signal is the mark signal respectively. In this way, uniformity as well as stability of printing can be secured, at the same time increasing printing speed.
