2.15 Using Control Representation Mode
The Control Representation Mode is used to print out unprocessed data
or commands sent from the host computer. This procedure is sometimes
referred to as ‘‘dumping.’’ The printing of unprocessed data (in the form
of characters and symbols) is convenient for debugging programs. If a
specified character is undefined, a hexadecimal representation is printed
in its place.
This section explains how to print the character listing. For additional
information about Control Representation Mode, consult the Digital ANSI-
Compliant Printing Protocol Level 3 Programming Reference Manual.
NOTE: If the file does not fill the page buffer completely, the remaining
data can be printed by pressing On Line toplace the printer off line, and then
pressing FormFeed to print the partial page.
