Developer Guidelines¶

Adding New Printer Support¶

To add support for a new printer brand, implement the PrinterInterface:

class NewPrinter(BasePrinter):
    """New printer implementation."""

    # Required methods
    async def connect(self) -> bool:
    async def disconnect(self) -> None:
    async def get_status(self) -> PrinterStatusUpdate:
    async def get_job_info(self) -> Optional[JobInfo]:
    async def list_files(self) -> List[PrinterFile]:
    async def download_file(self, filename: str, local_path: str) -> bool:
    async def pause_print(self) -> bool:
    async def resume_print(self) -> bool:
    async def stop_print(self) -> bool:
    async def has_camera(self) -> bool:
    async def get_camera_stream_url(self) -> Optional[str]:
    async def take_snapshot(self) -> Optional[bytes]:
