const SYSTEM_PRINTER_JSON_HELP: &str = r#"# System printer JSON

Use this payload when registering the `System` printer plugin. Leave fields out to fall back to BeepZone's legacy sizing.

## Core fields
- `paper_size` *(string)* — Named stock such as `A4`, `Letter`, `A5`, or `Custom`.
- `orientation` *(string)* — Either `portrait` or `landscape`. Selecting `landscape` rotates the page 90°; any custom width/height you supply are interpreted in the stock's natural (portrait) orientation and the app flips them automatically while printing.
- `margins` *(object in millimetres)* — Trim space on each edge with `top`, `right`, `bottom`, `left` properties.
- `scale_mode` *(string)* — Scaling behavior: `fit` (proportional fit), `fit-x` (fit width), `fit-y` (fit height), `max-both`, `max-x`, `max-y`, or `manual`.
- `scale_factor` *(number ≥ 0)* — Manual multiplier applied according to scale_mode.
- `duplex`, `color`, `quality` *(optional)* — Mirrors the underlying OS print options.
- `copies` *(number)* — Number of copies to print.
- `custom_width_mm` / `custom_height_mm` *(numbers)* — Provide both to describe bespoke media using the printer's normal portrait orientation.

## Layout control
- `center` *("none" | "horizontal" | "vertical" | "both" | null)* — Centers content when not disabled.
- `center_disabled` *(bool)* — When `true`, ignores the `center` setting while keeping the last chosen mode for later.

## Direct print (optional)
- `printer_name` *(string | null)* — If set, the System plugin will attempt to print directly to this OS printer by name.
- `show_dialog_if_unfound` *(bool, default: true)* — When `true` (or omitted) and the named printer can't be resolved, a lightweight popup chooser appears. Set to `false` to skip the chooser and only open the PDF viewer.
- `compatibility_mode` *(bool, default: false)* — When `true`, sends NO CUPS job options at all - only the raw PDF. Use this for severely broken printer filters (e.g., Kyocera network printers with crashing filters). The printer will use its default settings.

## Examples

### Custom Label Printer (e.g., ZQ510)
```json

    "margins": {
        "top": 0.0,

    "center": "both",
    "center_disabled": false,
    "printer_name": "ZQ510",
    "show_dialog_if_unfound": true
}
```

### Standard A4 Office Printer
```json

    "paper_size": "A4",
    "orientation": "portrait",
    "margins": {
        "top": 12.7,
        "right": 12.7,

        "left": 12.7
    },
    "scale_mode": "fit",
    "scale_factor": 1.0,
    "color": true,
    "quality": "high",
    "copies": 1,
    "duplex": false,

const PDF_PRINTER_JSON_HELP: &str = r#"# PDF export JSON

The PDF plugin understands the same shape as the System printer. Use the optional flags only when you want the enhanced layout controls; otherwise omit them for the classic renderer settings.

## Typical usage
- Provide `paper_size` / `orientation` or include `custom_width_mm` + `custom_height_mm` for bespoke sheets. Enter the measurements in the stock's natural portrait orientation; landscape output is handled automatically.
- Reuse the `margins` block from your system printers so labels line up identically.
- `scale_mode`, `scale_factor`, `center`, `center_disabled` behave exactly the same as the System plugin.
- The exported file path is still chosen through the PDF save dialog; these settings only influence page geometry.

## Available scale modes
- `fit` — Proportionally fit the design within the printable area
- `fit-x` — Fit to page width only
- `fit-y` — Fit to page height only
- `max-both` — Maximum size that fits both dimensions
- `max-x` — Maximum width scaling
- `max-y` — Maximum height scaling
- `manual` — Use exact `scale_factor` value

## Example

```json
{
    "paper_size": "Letter",
    "orientation": "portrait",
    "margins": { "top": 5.0, "right": 5.0, "bottom": 5.0, "left": 5.0 },
    "scale_mode": "manual",
    "scale_factor": 0.92,
    "center": "horizontal",
    "center_disabled": false
}
```
