Example:
In contrast to the ESC sequences of the standard, character set and
graphics commands for the document printer- specific additional com-
mands (CSI sequences), the command parameters n, n1, etc. are co-
ded as ASCII values. For example, three bytes are transferred for a
three- figure parameter value n = 123 (see “Additional commands”
chapter).
Program examples
All instructions in the program examples to demonstrate the standard control
commands are represented independently of a certain programming language.
This is done by formulating the program lines in a colloquial pseudo code. In
practice, this pseudo code, depending on the programming language used, must
be converted into the appropriate program instructions.
Q Parameter value of n must be encrypted binarily
R
