^XZ — End Label

Plain English

This tells the printer "I'm done describing this label, go ahead and print it" — `^XZ` ends the format AND flushes the accumulated buffer to the print engine for execution.

When to use

Always. It is the print trigger — without `^XZ`, the printer holds the format in its buffer indefinitely and nothing prints. The `^XA`…`^XZ` pair brackets every executable label.

Syntax

^XZ

Example

^XA
^FO50,50^A0N,30,30^FDDone!^FS
^XZ

`^XZ` at the end triggers the print. Remove `^XZ` and the printer waits forever.
