Chapter 11— Printer Escape Commands
106 EasyCoder PL-Series Printer Programmer’s Reference Manual
Set and Read Code Command
Purpose: Printer command sessions normally start with the “!” character. When you
use the printer in Generic Text mode (or Line Print mode) and if you
expect to print the “!” character in that mode, then you must change the
CCL code. You change this mode using the Redefine CCL Code
command.
Send the following sequence to redefine the code:
Set CCL Code: ESC (0x1b) '}' (0x7D) 'W' (0x57) '1'
(0x31) < new code >
(SETCCL.LBL)
Where { new code } is a one-byte character representing the new CCL code.
Once the CCL code is changed, you should start all CCL sessions with the
new CCL code. For example, if CCL code is changed to “~”, then instead
of issuing a ! UTILITIES command to the printer, you should issue ~
UTILITIES.
The printer retains the new CCL code for as long as it remains turned on.
If the printer is turned off and back on again, it reverts back to normal
operations and expects “!” as the CCL code.
Send the following sequence to read the CCL code:
Read CCL Code: ESC (0x1b) '}' (0x7D) 'R' (0x52) '1'
(0x31)
(READCCL.LBL)
After the above command is issued, the printer returns the one-character
CCL code.
Format:
{ escape } { command } [ parameters ]
where:
{escape}: The ESC character (0x1b).
{command}: Choose from the escape commands in this section.
[parameters]: Parameters for the escape commands.
Note: The escape commands should not be used while in a control/utility
session (! UTILITIES... PRINT or ! 0... PRINT).
