Common problems when printing labels

These are the five most frequently encountered problems in printing bar code
labels:
• The message does not end with the printer command <ETB>.
• The program contains printer commands that the printer does not recognize.
The printer ignores invalid commands and, when possible, substitutes a
default value.
• The label data contains too many characters for its field on the label.
• The label is physically too small to hold the data.
• The twinax interface has not been installed and tested correctly.
Twinax Interface
Response
The twinax interface ignores messages
containing protocol errors and records the
error in the twinax interface error log.
Instructions for printing the error log are on
page 31.
The printer ignores bad printer commands,
substitutes default values where applicable,
and continues to the next command. No
errors are reported or logged.
Errors that occur within the twinax interface
are recorded in the twinax interface error log.
An opcode error is an example of an error that
occurs within the twinax interface. The error
