What it does
The Code 39 part carries the six-digit ECI number; the MicroPDF417 part, always four columns, carries the rest and the firmware picks its mode from the data length. The guide says the command defaults already comply with the TCIF standard at any printhead density.
Field data: the ECI number (exactly six digits), a comma, a serial number of up to 25 alphanumeric characters, then optional comma-separated fields of up to 25 characters each, 150 bytes in total. If the seventh character is not a comma, only the Code 39 symbol prints.
In the preview
This command changes the printed label, but Labelixa's preview does not apply it yet. The linter reports it as ZPL1002, so you know the preview and the print will differ.
