# printInteractionController(_:cutLengthFor:)

Asks the delegate for a length to use when cutting the page.

```
optional func printInteractionController(_ printInteractionController: UIPrintInteractionController, cutLengthFor paper: UIPrintPaper) -> CGFloat
```

## Parameters

`printInteractionController`

The shared instance of [`UIPrintInteractionController`](/documentation/UIKit/UIPrintInteractionController) that is managing the print job.

`paper`

A [`UIPrintPaper`](/documentation/UIKit/UIPrintPaper) that specifies the maximum physical and printable areas of the page.

## Return Value

The physical length of the page in points.

## Discussion

Some printers can cut a roll of print paper at a particular length. If you implement this method in your delegate, then it may be called during a print job. Your delegate should determine the length in which the content fits and return this value. When printed, the paper will be cut to this length.
