Printer Escape Commands
A.
SET AND READ CODE Command
Printer command sessions normally start with the ‘!’ character. When the printer is used in Generic
Text Mode (or Line-Print Mode) and if the user expects to print the ‘!” character in that mode, then
the CCL code must be changed.
Set CCL Code
ESC(0x1b) ‘}’(0x7d) ‘W’(0x57) ‘1’(0x31) <new CCL code>
Where
{new CCL code} is a one-bye character representing the new CCL code.
Once the CCL Code is changed, all CCL session should be stared with the new CCL code.
The printer will retain the new CCL code for as long as it remains powered.
Follow sequence to read the CCL code:
Read CCL Code
ESC(0x1b) ‘}’(0x7d) ‘R’(0x52) ‘1’(0x31)
After the above command is issued, the printer will return the one-character CCL code.
