Once a character has been defined as the ESC character, it cannot
be printed or used as a normal character. However, it is not neces-
sary to have an ESC character defined permanently. When the ESC
character has served its purpose, it can be deleted.
When you have defined an ESC character in the converter, the
following facilities will be available to you:
• Sending HEX codes (00 to FF) directly to the printer
• Changing the settings of the converter
• Sending special commands to the converter (e.g. to save the
contents of the temporary memory in the permanent memory).
When the converter receives the characters following the ESC
character, it will use them for special purposes.
Below you will find examples of FSL commands, where "%" is the
defined ESC character :
Escape Sequence Function
%Y6,100% Set Function 6: Maximum Print Posi-
tion (MPP) to 100
%Y8,04% Set Function 8, LU1 Language, to
Belgian
%Y61,1,1B,26,6C,32,58% Define user string 1 with the PCL
command "print 2 copies"
NOTE:
In FSL mode, the notations ":" and ";" have special
meanings in the FSL Functions 75 and 80. See
D62071, the section "Overwriting the Translate
Tables" for more information.
