According to the invention the printer is characterised in that the detecting means detects, at the beginning of each set of print data, codes representing blank graphics characters, and comprises means for converting the blank graphics character codes into codes representing text spaces, whereby the control system, on detecting the converted codes, moves the print head past the positions for printing the blank graphics characters into the correct position for printing the character corresponding to the first of the character codes.</p> |
