Abstract
The apparatus comprises a dot printer (24) and a control unit for the printer connected to the line in parallel with a video display, the control unit is capable of processing the data received and storing it temporarily in a page memory in transcoded form in such a way as to associate with each character the relative print attributes and to be able directly to address a character generator. The control unit is capable of taking the transcoded data from the page memory for controlling the printer. The character generator comprises a portion for the alphanumeric characters, a portion for semigraphic characters and a portion for decoding colors with a corresponding grey value. The semigraphic characters are produced on a matrix of 10.times.12 dots in such a way that, for each grey value, the horizontal and vertical distance of the character dots of the same color remains constant.
