T5023/5023+ - Programming Guide 13
Programming interface (General)
This chapter contains general information on how the functions of the document
printer can be activated by a user program, i. e., how the document printer can
be programmed. This chapter also explains the functions which can be activated
by means of the program in a short, comprehensive summary.
Encryptions/Codes
The print functions of the document printer are initiated from a program in which
unique numeric encryptions (codes) representing characters and commands are
transmitted from the computer to the printer. The individual codes stand for prin-
table characters (letters, numbers, punctuation marks, mathematical symbols)
or control codes, which cause certain actions (for example, document ejection,
deletion of characters, carriage return).
