Advanced Features-Twinax; Command Pass-Thru - Black Box PC124C Installation Manual

7. Advanced Features—Twinax
There are several advanced features in the interface for accessing special functions
of the attached printers, which are not normally available on the IBM 3812-1
printer:

• Command Pass-Thru™

• User-Defined Strings
• User-Defined Fonts
• Color Printing
• Bar Code Printing
Each of these features is described on the following pages.
7.1 Command Pass-Thru™
The Command Pass-Thru feature allows you to access all of the built-in features of
your printer, even if these features aren't normally available through the host
software. Command Pass-Thru lets you place printer- specific command sequences
into the data sent to the printer. The interface recognizes these special sequences
and "passes the command through" to the printer. The steps below describe how
to use Command Pass-Thru.
1. Find the command for the print feature in the printer's manual.
2. Convert the printer command to hexadecimal.
3. Place the EBCDIC delimiter, as defined by a host-download command (refer
to Chapter 3, Configuration) in the document at the point you want the
feature to take effect. This signals the start of the print feature. Enter the
beginning printer command, then enter the delimiter again. You may enter a
space between hexadecimal code pairs to make the command easier to read,
but do not put spaces between the delimiter and the hexadecimal characters.
4. Move the cursor to the point in the text that you want to end the print
feature. Enter the delimiter, followed by the ending printer command, and
then the delimiter again, into the document.
