SAPScript barcode printing not using character format

Hi,

Recently our barcode printer is not working anymore so we decides to replace the printer.

However, there is some issue with the form used to print the barcode.

This sapscript form already been created long time ago while I'm not in the organization yet.

When I check the form, I found out that instead of using normal character format to print barcode, i.e. <BC>&Number&</BC>, the sapscript was created using another approach that I don't understand.

One of the line is like below :

1a4202300210020&ANLAV-ANLN1&&ANLA-ANLN2&&ANLA-BUKRS&

The line is using standard paragraph format and as you can see, it is not using character format to print barcode. However, in the old barcode printer, it will print barcode perfectly while in the new printer it will be printed like this:

1a420230021002030000000031200000300

It seems like 1a4202300210020 is some kind of code that convert the next number into a barcode in specific printer.

Can anyone please enlighten me on what kind of approach it is and how to resolve my barcode printing issue after we replace the old printer. Thank you.
