COMMUNICATIONS DIAGNOSTICS TEST
The communications diagnostics mode is a troubleshooting tool for checking the interconnection between the printer and the host. When "diagnostics" is selected, all data sent from the host to the printer will be printed as straight ASCII hex characters. The printer prints all characters received including control codes, like CR (carriage return). A sample printout is shown below.
NOTE: This label will be inverted when printed.

To put the printer in "diagnostics" mode, press Setup/Exit once, then Increment (+) until Communications is displayed on the LCD. Press the Select Key, then the Increment (+) to display Diagnostics. You may be prompted for a password. The default password is 1234. After entering the password into the display, press the "Select" key, then change to the desired Communications mode, Normal or Diagnostics.
NOTES on Diagnostic printouts:
An FE indicates a framing error.
An OE indicates an overrun error.
A PE indicates a parity error

For any errors, check that your communications parameters are correct. Set the print width equal to or less than the label width used for the test.
