Abstract
A method and apparatus for printing characters in bold form in a typing system. As disclosed, characters entered through an input device such as a keyboard are printed on paper, placed in a display and stored in memory substantially as they are entered. After a group of characters, such as a line of characters, have been entered and printed, those characters which are to be printed in bold form are identified from the information stored in the memory. The thus-identified characters are then printed a second time at a position slightly offset from that of the first printing of each of the characters.
Claims6
A method of printing characters in bold form in which a character is printed a first and a second time, with the second printing of the character occurring at a position offset from that of the first printing of the character, comprising the steps of:
- printing a group of characters, such as a line of characters, substantially as the characters in the group of characters are entered through an input device;
- substantially simultaneously with said printing, storing information related to said characters in the group of characters in a memory and displaying said characters in a display;
- after printing the group of characters, determining from the information stored in the memory which characters, if any, in the group of characters are to be printed in bold form;
- and
- printing each of said characters which are determined to be printed in bold form a second time at a position offset from that of the first printing of each of said characters.
In a typing system having (a) a printer, including a printhead and a printhead drive for moving the printhead relative to a medium upon which characters are to be printed, (b) input means for entering characters to be printed, and (c) a display for displaying entered characters, the improvement comprising:
- means for controlling the printhead and the printhead drive to print a group of characters, such as a line of characters, substantially as characters in the group of characters are entered through the input means;
- means for displaying entered characters on the display substantially simultaneously with printing of the characters;
- means for storing information related to entered characters, including information indicative of characters to be printed in bold form, substantially simultaneously with printing of the characters;
- means for identifying, from said stored information related to entered characters, characters in the group of characters which are to be printed in bold form;
- and
- means for controlling the printhead and the printhead drive to print each of the identified characters a second time, at a position offset from that of the first printing of each of the identified characters.
