Tools

• barcode_png

  Generate a single barcode as a PNG image (Code 128, QR, DataMatrix, EAN-13, UPC-A, PDF417 and more). For a full label with text and layout, write ZPL and use zpl_preview instead.

  shallow
• convert_zpl_dpi

  Rescale ZPL between printer resolutions (203/300/600 DPI): coordinates, fonts, barcode module width and label size are scaled. Embedded ^GF/~DG image data is NOT scaled; the response says so instead of silently passing it through.

  shallow
• cpcl_validate

  Lint CPCL label code; returns positioned findings with severity as JSON.

  shallow
• epl_validate

  Lint EPL/EPL2 label code; returns positioned findings with severity as JSON.

  shallow
• explain_zpl

  Full health report for a ZPL label: sectioned findings (syntax, size/DPI, orientation, barcodes, fonts, graphics memory, job behaviour) with an honest score — sections that cannot be assessed say so and are excluded from the score.

  shallow
• language_detect

  Detect which printer language raw label code is written in (ZPL, EPL, TSPL or CPCL). Heuristic: returns the language plus a confidence TIER (high/medium/low) and signal codes — not a probability.

  shallow
• tspl_validate

  Lint TSPL/TSPL2 label code; returns positioned findings with severity as JSON.

  shallow
• zpl_command_help

  Explain a single ZPL command: syntax, parameters with types/ranges/options, a fragment example and whether the Labelixa renderer draws it. Data comes from the same catalog that powers the public command reference pages.

  shallow
• zpl_compatibility

  Compatibility RISK analysis of ZPL code against a specific printer model (e.g. 'zebra-zd421'). NOT an emulator and never says 'it works': reports the model's language posture with evidence level and size-rule findings.

  shallow
• zpl_preview

  Render ZPL label code and return the label as a PNG image. Use this to SEE what ZPL output looks like — LLMs can write ZPL but cannot otherwise verify the visual result. One call renders one label (use `index` to pick a label from a multi-label stream).

  shallow
• zpl_validate

  Lint ZPL code and return structured diagnostics: unknown commands, missing ^FS, out-of-range parameters, fields outside the label boundary. Run this before zpl_preview when generating ZPL.
