Claims

[Scope of utility model registration request]

A dot printer that prints on paper based on character data based on character codes supplied from an external device has a buffer memory that stores a small number of pages of the character data, and a buffer memory that stores dot data corresponding to various character data. a character generator, a dot data memory that stores dot data output from the character generator, a printing section that performs dot printing based on the dot data, and a central processing unit; supplying the character data in the character data corresponding to the storage capacity of the dot data memory from the first character data of each line to the character generator, and as a result, storing the dot data output from the character generator in the dot data memory; ,
A dot printer characterized in that the dot data in the dot data memory is supplied to the printing unit, and further, by repeating the above-described operations, all the character data in the buffer memory is printed in dots.
