Print APIAPIs
APIs
The Print API enables document printing through the device's native print dialog (such as AirPrint on iOS or the system print dialog on Android). This API is designed for printing documents to standard printers, and does not support direct printing to receipt printers.

print
(src: string) => Promise<void>
required
Trigger a print dialog.
The src must be either:
- A relative path that will be appended to your app's application_url
- A full URL to your app's backend that will be used to return the document to print
Supported document types:
- HTML documents (recommended for best printing experience)
- Text files
- Image files (PNG, JPEG, etc.)
- PDF files (Note: On Android devices, PDFs will be downloaded and must be printed using an external application)
