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

beprogrammed. This chapter also explains the functions which can be activated

by means of the program in a short, comprehensive summary.

The print functions of thedoc umentprinter are initiated from a program in which

uniquenumeric 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).
