Graphics commands
158 T5023/5023+ - Programming Guide
– General notes on the command description can be found in the
chapter “Standard commands” in the sections “Description com-
ponents”, “Coding of decimal command parameters” and “Program
examples”.
– The document printer works in different graphics modes. A gra-
phics mode is labelled by the number of print head needles addres-
sed when printing, (8 needles or 24 needles) and by the horizontal
dot spacing (60 – 360 characters per inch).
– The graphics commands switch on one of the graphics modes (ex-
ception: ESC ?). A defined set of the subsequently transferred data
is interpreted as a dot pattern, similar to the definition of a charac-
ter. The exact quantity depends on the selected graphics mode and
the parameters specified in the command.
– In many cases, graphics can also be displayed with a commercially
available program on the screen of the computer and then printed
as a so-called “Screen Dump”. As long as the program uses the ap-
propriate graphics commands, the screen image and the printout
will match.
– All the graphics modes of the document printer can be switched on
using the command ESC * .
