In the attached except from the ZPL Programmers manual, it shows both manual commands to switch between subsets A,B, and C. I understand the reason for switching between these sets but I'm unsure if it's ok just to use Automatic mode and let the printer determine when to switch, or does the presence of manual Subset switching invocation mean that it might result in a better result to do it manually ?
ZPL Code128 Subset switching - is Automatic mode enough ?// Expert user has replied. |

Automatic mode for Code128 usually works, but it is permissive. If you want to force the output to only be numeric, that is where the subsets come in handy. Subsets also may make the output barcode less wide, as automatic will assume a full utf-8 character encoding and will encode bytes that may not be nessesary with the more limited character subsets.
