Description

The Print plugin does not allow configuring which projection is selected by default when the print dialog opens. The selection always fell back to the map projection or EPSG:3857.

Solution

Projection options are already supported via projectionOptions.projections (list of available CRS in the dropdown). The plugin should now support an optional default projection so the dialog opens with a chosen CRS pre-selected.

Configuration

Under the Print plugin cfg, use projectionOptions.defaultProjection. It should be one of the values from your projectionOptions.projections list.

Example (localConfig.json):

{
  "name": "Print",
  "cfg": {
    "projectionOptions": {
      "projections": [
        {"name": "EPSG:32122 (Ohio North)", "value": "EPSG:32122"},
        {"name": "EPSG:3857", "value": "EPSG:3857"},
        {"name": "EPSG:4326", "value": "EPSG:4326"}
      ],
      "defaultProjection": "EPSG:32122"
    }
  }
}

If defaultProjection is omitted, behavior is unchanged (map projection or EPSG:3857).

Other useful information

Note: For any projection other than EPSG:4326 or EPSG:3857, you must define it in projectionDefs (with code, def, extent, worldExtent) so the map and preview render correctly.
