Troubleshooting
The Advantage RFID Thermal Printer is a dependable printer that
requires little user maintenance. When problems occur, it is important
to determine if hardware or programming is the cause.
Isolating Problems
Programming issues can often make the problem appear hardware
related. Use the following steps to determine the source of the problem.
Run a Printer Self Test
If the printer will not print a self-test label, the problem is most likely a
hardware problem. 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.
Print 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:
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
! 0 100 20 1
STRING 8X8 10 10 HELLO
