Please help with the following situation:

Using ZPL script, I have to generate a barcode with GS1-128 (formally known as Code 128). I have the following specs:

The ideal way to label products is with complex barcodes with delimiters (cf. the GS1 standard, on the GS1-128 barcode model).
The following information is contained in the same barcode:

2. SSCC (only for pallet label);
3. EAN code;
4. Quantity;
5. Expiration date;
6. Lot.

LABEL STRUCTURE EAN 128
(00) - 18 numeric characters
       Example: 712300000000125672 - SSCC - Unique pallet code;
(01) / (02) - 14 numeric characters
              Example: 02911225000004 - EAN article (includes control key);
(3100) - 6 numeric characters, weight in kilograms without decimals
         Example: (3100)000700 represents 700 KG.
(3101) - 6 numeric characters, weight in kilograms with a decimal
         Example: (3101)000700 represents 70.0 KG.
(3102) - 6 numeric characters, weight in kilograms to two decimal places
         Example: (3102)000700 represents 7.00 KG.
(3103) – 6 numeric characters, weight in kilograms to three decimal
         Example: (3103)000700 represents 0.700 KG.
(37) - numeric characters, variable length up to 8 characters - number of packages / pallet.
(17) - 6 numeric characters
       Example: 210730 - Expiry date in AALLZZ format
(10) - alphanumeric characters, variable length up to 20 characters
       Example: 3245AB / 60 - Lot.CODE.

In order for the system to read the information in the barcode correctly, it can be created in two ways:

  1. The first way is by placing all fields with variable length at the end of the barcode ((37) and (10)) without the need to insert a GS128 separator in the label.
    EXAMPLE:
    PALLET CODE (SSCC) must always be created separately on the pallet label.
    SSCC code:

    SSCC Code Part 2 of bar code

    How it looks scanned:

  2. A second way to create these labels is by inserting the GS128 separator after completing the variable length fields ((37) (10)) when they are inside the barcode.
    PALLET CODE (SSCC) must always be created separately on the pallet label.
    Example of pallet label with GS128 separator.

    SSCC code

    It looks scanned like this:

    Last part of code:

    Looks scanned like:

Thank you very much.

    That is a description, but what is your actual question? – GSerg Sep 17 '21 at 12:00
  • Hi GSerg, the question is how to generate the ZPL script with the request information? Thank you! – Raoul Osiceanu Sep 17 '21 at 12:05

    You have pieces of text, and you list them all together in the `^BC` command specifying mode `D`? Page 92 of the [manual](https://www.zebra.com/content/dam/zebra/manuals/printers/common/programming/zpl-zbi2-pm-en.pdf). – GSerg Sep 17 '21 at 12:15
