I have these instructions for a barcode

SUBSET C FEATURE OF CODE 128
To optimize the length of the barcode for printing use the Subset C feature of Code 128 to
automatically ‘compress’ the long strings of numerical characters.
Some printers and barcode fonts require the user to pass encoded information to the application.
The actual values are specific for each printer or font. A general illustration is presented below.


The data format before printing is:
Start Code 128 Subset B 1ABC Shift to Subset C 123456789012345678901234 EndCode128

I created the first 4 digits using the barcode128 subset b for my first 4 characters and then selected the last remaining characters in a new barcode128 subset C then I snapped them together using snapping points.

This is not scannable.

So then I tried presstalk using this:

showbarcodecode128(&barcodeb,1,12,false)
rmoveto(0,-1)
showbarcodecode128(&barcodec,2,12,false)

The barcode has the same look of the original barcode I made but when outputting to a pdf the barcode doesn't even look the same then what is viewed.

The question is how do I use 2 different subsets into one barcode.

This is the string in my data:
2LAY511123456701000010600105

2LAY (Subset B)
remaining characters (Subset C)

You can switch subsets in the middle of a EAN 128 barcode by inserting the appropriate control character in the data:


So with your example, the data would lokk like this:

The above litterally means:

• Switch immediately to subset B (^104)
• Print these subset B characters (2LAY)
• Switch to subset C (^105)
• Print these subset C characters (511123456701000010600105)
