# run()

Runs the print operation on the current thread.

## Declaration

```swift
func run() -> Bool
```

## Return Value

Return Value true if the operation was successful; otherwise, false.

## Discussion

Discussion The operation runs to completion in the current thread, blocking the application. A separate thread is not spawned, even if canSpawnSeparateThread is true. Use runModal(for:delegate:didRun:contextInfo:) to use document-modal sheets and to allow a separate thread to perform the operation.
