Set Communications Mode
The communication diagnostics mode is a troubleshooting tool for
checking the interconnection between the printer and the host computer.
When
DIAGNOSTICS
is selected, all data sent from the host computer to
the printer prints as straight ASCII characters, with the hex value below the
ASCII text. The printer prints all characters received, including control
codes, like CR (carriage return). A sample printout is shown in
Communications Diagnostics Test on page 132
.
Notes on diagnostic printouts are defined as follows:
• FE indicates a framing error.
• OE indicates an overrun error.
• PE indicates a parity error.
• NE indicates noise.
Default: NORMAL MODE

Set Control Prefix Character
The printer looks for this two-digit hex character to indicate the start of a
ZPL/ZPL II control instruction. The “H” that is displayed indicates
Hexadecimal and is not part of the value.
Note •
Do not use the same hex value for the control, format, and
delimiter character. The printer must see different characters to
work properly.
