Troubleshooting
Most programming problems quickly resolve themselves with careful
examination of the offending label format or program code. When you
cannot solve a problem by simply reviewing your work, your best
approach is to start troubleshooting using the information in your
User’s Guide.
NOTE: Some programming problems can masquerade as hardware
problems. If your printer seems to be broken but the information in the User's
Guide does not point to a solution, review "Common problems and their
solutions" below.
If you know or suspect that you have a hardware problem, refer to
your User’s Guide. If you aren’t sure, try these preliminary tests to
help isolate the problem:
Run a printer self-test.
• If the printer will not print a self-test label, follow the
procedures in the User’s Guide to resolve that problem first. The
printer will not respond to incoming data if it will not print a self-
test label.
Print a proven label format.
• If you have a known-good label format, try printing it before
troubleshooting new label formats. If the proven format will not
print, look for a communication problem. If the proven format does
print, you will have eliminated most of the possible hardware-
related problems.
Try printing a label format written on your system.
• Sometimes the host operating system or text editor produces
data that is incompatible with the printer. Creating a simple label
format using the host system and sending the format to the printer
helps isolate this problem. Something like this will do:
