Hex Dump Mode

Hex Dump provides a way to print, in a readable form, all the data received by the printer. This tool is useful to

programmers for debugging programs when sending control codes and escape sequences 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.

When the printer is operating 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.

To select Hex Dump mode, enter Setup and use the

Advance Button to select the “INTERFACE MENU”.

Next use the

Enter Button to select “Emulation” and then use the Increment Button to select “Hex Dump”.

Now press the

Advance Button Until “Exit Setup, Save Changes” is displayed and press the Enter Button.

The printer will now reset and remain in Hex Dump mode until the “Emulation” is set back to another

appropriate value.

A sample hex dump is shown below. Note that each line shows eight characters, first in hexadecimal format,

then in printable ASCII format. All unprintable ASCII characters (0x00-0x1F) are represented by a period.

Note: 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. When using the printer in Hex Dump mode using the RS-232C Serial Interface, it is

recommended that the printer be configured for RTS/CTS handshake or XON/XOFF handshake.
