Common Issues
This section describes printing issues that you may encounter and
suggestions for resolving them.
Printer does not respond to incoming data.
Cause: The label format does not terminate with a proper END
command.
• Cure: Terminate all label formats with an END command,
unless specifically instructed otherwise by a particular command
description. Terminate every format line with a carriage return and
line feed.
Cause: The host system is not sending pure ASCII data.
• Cure: Check your system documentation to confirm that the
host is sending ASCII data. Some software uses formatting that is
incompatible with ASCII driven devices.
Cause: The label format contains an incompatible command. Some
commands will only work with certain printers.
• Cure: Rewrite the label format as required, removing
incompatible commands.
Cause: The label format contains extraneous control characters,
such as "@" or "#."
• Cure: Be careful when using reserved characters in label
formats. You can print the @ sign and other reserved characters,
but if you use such characters at the beginning of a line the printer
may "hang."
Cause: If you are sending data to a 4.25" portable printer it may be
asleep.
• Cure: Precede every label format sent to a 4.25" portable with
the proper wake-up string.
