Hex Dump mode provides a way to print, in a readable form, all the data received by the printer. This
tool is useful to programmers for diagnosing problems with control codes and escape sequences sent to
the printer. Hex Dump mode may also be used to detect what commands are being sent by a particular
software application to help determine which emulation mode is needed for that application.
To select Hex Dump mode, enter SETUP and use the MENU button to select the "TEST MENU".
Next use the ITEM buttons to select "Test Mode" and then use the VALUE buttons to select "Hex
Dump". Now press ONLINE to reset the printer. The printer will now remain in Hex Dump mode
until "Test Mode" is set back to "Off" or some other value.
A sample hex dump is shown below. Note that each line shows sixteen characters, first in hexadecimal
format, then in printable ASCII format. All unprintable ASCII characters (printable characters are
from 21 hex to 7E hex inclusive) are represented by a period.

When the printer is executing in Hex Dump mode, control characters and escape sequences sent to the
printer are not recognized or processed. The hexadecimal representation of the control characters and
escape sequences will appear in the hex dump, but no other special processing will occur.
In particular, note that ETX/ACK handshake will not operate properly in Hex Dump mode. When an
ETX is received by the printer, its hexadecimal representation will be printed in the hex dump, but no
ACK will be sent to the host computer.
recommended that the printer be configured for parallel I/O, serial I/O with hardware handshake, or
serial I/O with XON/XOFF handshake.
