Graphics modes
The graphics modes of the document printer are identified by the number of ver-
tically arranged dots, which the print head prints in a graphics line, i. e. by the
number of print head needles addressed during the printing operation:
– 8- dot mode
In one graphics line, 8 dots spaced at 1/60 inch can be printed vertically. In
this mode, six different horizontal dot spacings are available.
– 24- dot mode
In this mode, 24 dots spaced at 1/180 inch can be printed vertically. Five dif-
ferent horizontal dot spacings are available.
All graphics modes can be switched on using the command ESC * (m) (n1) (n2)
by means of the selection of the parameter s. The following table shows the dot
densities (in dots per inch) of the various graphics modes and the corresponding
parameter s:
