ようなドツトラインプリンターも知られている。However, the printing speed of conventional serial printers is 70 to 80 characters/minute, and that of line printers is 170 characters/minute.
It was quite slow compared to ~180 characters/minute, and speeding up was desired. For example, as a line printer,
As described in Japanese Patent Application Laid-open No. 6-29781, Japanese Patent Application Laid-open No. 56-54584, and Japanese Patent Application Laid-open No. 56-99685, each digit character for one line to be printed out of a group of characters on a type drum. When the type characters reach the printing position, a printing hammer is generally driven by a printing magnet to strike the paper against the surface of a type drum to perform printing. Dot line printers such as the Dot Line Printer are also known.
