ZPL1001 — Unknown command

The command is not in the ZPL vocabulary. Printers skip what they do not understand, so the label prints without it and nobody is told.

How to fix it

Check the spelling against the ZPL command reference; the quick-fix deletes the command. When the code differs from a real command by a confusable character, ZPL1003 names the intended one.
