Diagnostics
The Communication Diagnostics Mode is a troubleshooting
tool for checking the interconnection between the printer and
the host. When “Diagnostics” is selected, all data sent from
the host to the printer will be printed as straight ASCII hex
characters. The printer prints all characters received including
control codes, like CR (Carriage Return). A sample printout is
shown in Figure 18 on page 69.
NOTES on diagnostic printouts:
• An FE indicates a framing error.
• An OE indicates an overrun error.
• An PE indicates a parity error.
• An NE indicates noise.
For any errors, check that your communication parameters are
correct. Set the print width equal to or less than the label
width used for the test. See page 34 for more information.
Selecting Prefix and Delimiter Characters
Prefix and delimiter characters are 2-digit hex values used within the ZPL/ZPL II formats
sent to the printer. The printer uses the last prefix and delimiter characters sent to it,
whether from a ZPL II instruction or from the front panel.
NOTE: To change the values, refer to the ASCII code chart on page 94 for character
choices. DO NOT use the same hex value for the Control, Format, and Delimiter character.
The printer needs to see different characters to function properly.
