Represents a self-contained ZPL instruction ready for rendering.

Unlike AST commands, instructions are calculated based on the cumulative state of the parser (e.g., coordinates are absolute, fonts are resolved).

Variants

PageBreak

Starts a new page. Emitted between consecutive ^XA...^XZ blocks.

text: String

Text content.

reverse_print: bool

Whether to print white-on-black.

color: Option<String>
