Editing Existing Fields
If you make a mistake in a label format, you may not have to download
the entire format again depending on the severity of the mistake. You can
change a specific field in a format by sending a command in Program
mode. You can modify just the incorrect format fields instead of having to
download the entire format again.
When the printer is in Program mode, it uses a field pointer to point to
the field to be modified. The pointer continues to point to the most
recently selected field until you select a different format or field.
For the next example, assume that you used the following format:

<STX><ESC>C<ETX>

<STX>H1;o80,120;f0;c0;d0,16;h1;w1;<ETX>

<STX>B4;o80,0;f0;c0,1;h50;w1;d0,11;i0;p@;<ETX>

<STX>R;<ETX>
Saves and exits to Print mode
To change the height and width of field 3 to 2 dots, download this
command string:
<STX><ESC>P;F3;H3;h2;w2;R;<ETX>
The following table describes each command in this string:

command in a message, all commands in Program mode must end with this
terminator.
