A retail system needs an EAN-13 barcode for a new product and you only have the 12-digit prefix, not the final check digit.
First 12 digits
012345678901
EAN-13 barcode
0123456789012 (check digit 2 computed and appended)
EAN-13's 13th digit is a checksum: alternate digits are weighted ×1 and ×3, summed, and the digit needed to reach the next multiple of 10 is appended (here, 2). The tool computes it for you and renders the bars at the correct module width, so a scanner will actually read it instead of rejecting an invalid code.

Code 128 is versatile and supports the full ASCII set. Use EAN-13 or UPC-A for retail products, and Code 39 for simple alphanumeric labels.
Check that the data matches the format requirements (e.g., EAN-13 needs exactly 12 or 13 digits) and that the print resolution is sufficient.
