Black Box PC124C Installation Manual page 34

The command itself will not be printed if it was entered correctly, but the effect
of the command should be evident (change in the print orientation, paper-size
selection, and so on). If any part of the command is printed, the interface did not
recognize the command because of a problem in the format. Check the syntax of
the command and send the command again.
Host-download commands sent to the Laser Card take effect immediately and
stay only in the interface's active memory. If you want the commands to be active
when the printer is powered on, they must be stored permanently by the download
command Z99.
The tables on the following pages provide a description of each command and
how it is used.
Follow these steps to enter a host-download command.
1. Type the delimiter &% (or a custom delimiter as described in the table) in
the document at the point you want the command to take effect.
2. Type an upper-case "Z".
3. Type the command number for the command you want to use, as shown in
the table.
4. Type a comma.
5. Type the command. No spaces are allowed. A space or invalid character in a
command causes the interface to ignore the command and resume printing
from the point the error occurred.
For example, to change the timeout value from the default of 8 seconds to 20
seconds, enter:
&%Z03,20
