Abstract

The typefont period 1 of printers employed in data processors can be used to represent plots consisting of dots. Such plots are not very accurate. More accurate plots are obtained by providing the printer, in addition to the normal period typefont, with typefonts having individual dots 2, 3, 4, 5 which are arranged in different positions than the period 1 on its typefont. Where, during plotting by means of these typefonts, several curve dots occur in one printing position, the lines have to be printed repeatedly.

Plotting by Means of Dots on Printer Typefonts

The typefont period 1 of printers employed in data processors can be used to represent plots consisting of dots. Such plots are not very accurate. More accurate plots are obtained by providing the printer, in addition to the normal period typefont, with typefonts having individual dots 2, 3, 4, 5 which are arranged in different positions than the period 1 on its typefont. Where, during plotting by means of these typefonts, several curve dots occur in one printing position, the lines have to be printed repeatedly.

Several dots per printing position can be generated in one pass if the printer is equipped with typefonts consisting of several dots. Typefonts 6 and 7 show complete 4 or 6 dot patterns. Typefonts with parts of these patterns are shown at 8 and 9.
