User-Defined Strings - Black Box PC124C Installation Manual

LASER CARDS FOR HP 4000 TWINAX AND COAX PRINTERS
For example:
The command ESC&d0D begins underlining and ESC&d@ ends underlining.
First convert the start command to the hexadecimal 1B 26 64 30 44 and the ending
command to 1B 26 64 40. And, if the delimiter is the default &% (hex 50 6C),
then enter the commands as follows:
This is an &%1B26643044&%underlined&%1B266440&% word. To print on the
printer as:
This is an underlined word.
Only characters from 00 to FF are recognized (letters must be in upper case).
Errors in the Command Pass-Thru sequence will cause the I-O interface to
ignore the command and printing will resume at the point the error occurred.
Although the command is displayed on the screen, the I-O printer interface
treats it as a command and does not print it. If part of the sequence is printed, you
have made an error in entering the codes; check your document and make sure
you are using the correct format and EBCDIC hexadecimal characters.
Command Pass-Thru may change the horizontal spacing. (Since word-
processing software sees printer commands as text, lines with comands in them
may be shorter than other lines when you print the document.) Avoid sending
codes that would move the print position during Command Pass-Thru. Since the I-
O card does not process these commands, it cannot keep track of the print
position changes; this may affect the position of following characters and page
layout.
You can also send the I-O Command Pass-Thru strings to the printer by typing
them on the host screen and pressing the screen print key.
Alternate Command Pass-Thru delimiters may be assigned by using the Z01
Command.

7.2 User-Defined Strings

To avoid keying in frequently used printer commands (which would appear in the
document as hex values embedded in Command Pass-Thru delimiters), you should
take advantage of the User-Defined Strings feature.
Using host-download command 04, assign the numbers 0 through 9 to
frequently used printer command strings.
