如果我知道iOS中的IP地址，如何获取斑马打印机名称？

import UIKit
import SystemConfiguration.CaptiveNetwork

func getIPAddress() -> String? {
    var address: String?
    var ifaddr: UnsafeMutablePointer<ifaddrs>?
    
    if getifaddrs(&ifaddr) == 0 {
        var ptr = ifaddr
        while ptr != nil {
            defer { ptr = ptr?.pointee.ifa_next }
            
            let interface = ptr?.pointee
            let addrFamily = interface?.ifa_addr.pointee.sa_family
            
            if addrFamily == UInt8(AF_INET) || addrFamily == UInt8(AF_INET6) {
                if let name = String(cString: (interface?.ifa_name)!), name == "en0" {
                    var hostname = [CChar](repeating: 0, count: Int(NI_MAXHOST))
                    getnameinfo(interface?.ifa_addr, socklen_t((interface?.ifa_addr.pointee.sa_len)!), &hostname, socklen_t(hostname.count), nil, socklen_t(0), NI_NUMERICHOST)
                    address = String(cString: hostname)
                }
            }
        }
        freeifaddrs(ifaddr)
    }
    
    return address
}

let ipAddress = getIPAddress()

import Foundation

class PrinterServiceDelegate: NSObject, NetServiceBrowserDelegate {
    var printerName: String?
    
    func findPrinters() {
        let browser = NetServiceBrowser()
        browser.delegate = self
        browser.searchForServices(ofType: "_printer._tcp", inDomain: "local.")
    }
    
    func netServiceBrowser(_ browser: NetServiceBrowser, didFind service: NetService, moreComing: Bool) {
        service.resolve(withTimeout: 10.0)
    }
    
    func netServiceDidResolveAddress(_ sender: NetService) {
        if let name = sender.name {
            printerName = name
            print("Printer Name: \(name)")
        }
    }
}

let printerDelegate = PrinterServiceDelegate()
printerDelegate.findPrinters()
