12. After the last field is sent, the host device terminates the formatting
session by sending an ASCII "E" (DEC 69, HEX 45) as a single
character string terminated by an ASCII CR (DEC 13, HEX 0D).
The label Printer will print the label from the field registers created
and return to the SYSTEM command processor.
The following is an example of the process explained in Section 4.10.
Power up the Printer, press FORM FEED and then the host device sends
out the following ASCII characters:
STX L CR
1 3 2 1
1 a 3 1
E
(Spaces in example are shown only for clarity.)
A label will print that looks like the sample below.
The STX L is a SYSTEM command that sends the Printer into the
LABEL FORMATTING interpreter.
