# UIPrintServiceExtension

An extension that locates and sets up a printer without a configuration profile.

## Declaration

```swift
@MainActor class UIPrintServiceExtension
```

## Overview

Overview Support cloud printing by creating an extension instead of requiring users to install a managed configuration profile to set up an AirPrint printer. Create an extension by subclassing UIPrintServiceExtension. By creating your own extension, you can expose a cloud printer destination to a UIPrinterPickerController. The extension matches printer destinations that fulfill the specified print-job attributes. Create an instance of UIPrinterDestination to describe a printer to the system. The extension can then search for the printer, or set of printers, using printerDestinations(for:). This method matches the requirements of a UIPrintInfo object and returns an array of UIPrinterDestination.
