Frequently Asked Questions

Finn raske svar

What is ZPL and why do I need to validate it?

ZPL (Zebra Programming Language) is a command language used to create labels for Zebra printers. Validation ensures your ZPL code is syntactically correct and will print correctly without errors.

What types of errors does this validator detect?

The validator detects syntax errors (missing parameters, invalid commands), structural errors (unclosed fields, incorrect nesting), and semantic errors (invalid values for parameters like font sizes or coordinates).

Can I validate ZPL files from different Zebra printer models?

Yes, the validator supports ZPL II which is compatible with most modern Zebra printers. It validates the core ZPL syntax that works across different printer models.

Is there a file size limit for ZPL file uploads?

The tool can handle typical ZPL files (usually under 100KB). For very large files, consider pasting the code directly into the textarea instead of uploading.
