Hex Trace Mode

The hex trace mode helps the user test and troubleshoot programs.
Use the hex trace procedure to get a hexadecimal printout of the
data stream sent to the printer. All data, including both control and
character data, print in hexadecimal instead of ASCII.

To activate hex trace mode:

1. Press and hold Tractor and then turn the printer on.

2. After a few seconds, release Tractor and the lights go out.

3. Start your application program. Be sure the printout is similar to

the hex trace sample shown. Two hexadecimal digits, followed
by a space, are printed for each byte of data sent to the printer.

4. The printer continues to print in hexadecimal until you turn the

printer off.
