Abstract (en)
[origin: EP0143995A2] A dot-matrx printer having a print head (26) and a platen (27) allowing the head (26) to bring dot characters in normal printing mode and an extra-wide-margin printing mode. The printer has a microprocessor (20) which decides, in accordance with printing data from an external device, whether or not a wide dot character is to be printed at the left margin or right margin. When it decides that a wide dot character is to be printed at the left or right margin, the microprocessor controls a print head driver (25) so that the head (26) may print dot characters in the extra-wide-margin printing mode. The print head (26) can therefore print wide dot characters together with characters of ordinary width, neatly and clearly.
