Wrap Data - Dymo LabelWriter SE300 User Manual

ESC W
DESCRIPTION
Causes the characters n1 and n2 to be echoed back to the host. As
soon as n1 is received by the printer, the printer, in turn, will
transmit n1 back to the host. Your program should wait to receive
n1 before outputting n2. If you don't wait, you may lose n1. If n1
and n2 are received successfully by the host, you can be
reasonably assured that there is a LabelWriter attached to the
serial port and your program can communicate with the printer.
