# runModalPrintOperation(_:delegate:didRun:contextInfo:)

Runs the specified print operation modally.

## Declaration

```swift
func runModalPrintOperation(_ printOperation: NSPrintOperation, delegate: Any?, didRun didRunSelector: Selector?, contextInfo: UnsafeMutableRawPointer?)
```

## Parameters

- `printOperation`: The print operation to run.
- `delegate`: The delegate to which the selector message is sent.
- `didRunSelector`: The selector of the message sent to the delegate.
- `contextInfo`: Object passed with the callback to provide any additional context information.

## Discussion

Discussion Overrides of printShowingPrintPanel: can invoke this method. When the panel is dismissed, delegate is sent a didRunSelector message. Pass the contextInfo object with the callback. The didRunSelector callback method should have the following signature: - (void)documentDidRunModalPrintOperation:(NSDocument *)document  success:(BOOL)success  contextInfo:(void *)contextInfo
