 bar code is the standard for the TCIF can tag telecommunications equipment.

TLC39 Barcode

The TCIF CLEI code, which is the MicroPDF417 barcode, is always four columns. The firmware must determine what mode to use based on the number of characters to be encoded.
Format:
^BTo,w1,r1,h1,w2,h2

How to Print TLC39 Barcode

Example:
 This is an example on how to print TLC39 barcode. The callouts identify the key components and are followed by a detailed description below:
Use the command defaults to get results that are in compliance with TCIF industry standards; regardless of printhead density.
1
ECI Number.
 If the seventh character is not a comma, only Code 39 prints. This means if more than 6 digits are present, Code 39 prints for the first six digits (and no Micro-PDF symbol is printed).
  • Must be 6 digits.
  • Firmware generates invalid character error if the firmware sees anything but 6 digits.
  • This number is not padded.
2
Serial number.
 The serial number can contain up to 25 characters and is variable length. The serial number is stored in the Micro-PDF symbol. If a comma follows the serial number, then additional data is used below.
  • If present, must be alphanumeric (letters and numbers, no punctuation).
This value is used if a comma follows the ECI number.
3
Additional data.
 If present, it is used for things such as a country code.
Data cannot exceed 150 bytes. This includes serial number commas.
  • Additional data is stored in the Micro-PDF symbol and appended after the serial number. A comma must exist between each maximum of 25 characters in the additional fields.
  • Additional data fields can contain up to 25 alphanumeric characters per field.
The result is:
