iOS UIPrintInteractionController打印

- (void)printData{

    //为打印做准备，创建一个指向sharedPrintController的引用
    UIPrintInteractionController *printer = [UIPrintInteractionController sharedPrintController];
    printer.delegate = self;

    //配置打印信息
    UIPrintInfo *Pinfo = [UIPrintInfo printInfo];
    Pinfo.outputType = UIPrintInfoOutputGeneral;//可打印文本、图形、图像
    Pinfo.jobName = @"Print for xiaodui";//可选属性，用于在打印中心中标识打印作业
    Pinfo.duplex = UIPrintInfoDuplexLongEdge;//双面打印绕长边翻页，NONE为禁止双面
    Pinfo.orientation = UIPrintInfoOrientationPortrait;//打印纵向还是横向

    //    Pinfo.printerID = @"";//指定默认打印机，也可以使用UIPrintInteractionControllerDelegate来知悉
    printer.printInfo = Pinfo;

    //设置页面范围 打印文字
//    UISimpleTextPrintFormatter *textFormatter = [[UISimpleTextPrintFormatter alloc] initWithText:@"哈护手霜按时哈哈"];

//    textFormatter.startPage = 0;//指定从哪一张开始打印0代表第一张

//    textFormatter.contentInsets = UIEdgeInsetsMake(36, 36, 36, 36);//72相当于1英寸，这样设置上下左右的边距都为0.5英寸

//    textFormatter.maximumContentWidth = 504;//(72x7.5)相当于打印宽度为7英寸

//    printer.printFormatter = textFormatter;

AirPrint可以直接打印一些内容。这些内容是 NSData, NSURL, UIImage, and ALAsset 类的实例，但是这些实例的内容，或者引用的类型（NSURL）必须是 image 或者pdf.
对于 image来说， NSData, NSURL, UIImage, and ALAsset 类型都可以的。对于PDF，只能使用 NSData, NSURL。然后需要将这些数据实例直接赋值给 UIPrintInteractionController实例的 printingItem 或者 printingItems 属性。

    // printer.printingItem = [UIImage imageNamed:@"LaunchImage"]; 
    printer.printingItems = @[[UIImage imageNamed:@"welcome_page2"], [UIImage imageNamed:@"LaunchImage"], [UIImage imageNamed:@"welcome_page1"],];

    printer.showsPageRange = NO;

    [printer presentAnimated:YES completionHandler:^(UIPrintInteractionController * _Nonnull printInteractionController, BOOL completed, NSError * _Nullable error) {

        if (!completed && error) {
            NSLog(@"Error");
        }
    }];

}

打印webView视图

初始化webView

- (UIWebView *)printWebView
{
    if (!_printWebView) {

        _printWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, Main_Screen_Width, Main_Screen_Height)];

        _printWebView.backgroundColor = HexRGB(0xf9f9f9);

        _printWebView.delegate = self;

        _printWebView.scalesPageToFit = YES;
    }

    return _printWebView;
}

加载视图

    NSURL *url = [NSURL URLWithString:@"https://www.baidu.com"];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    [self.printWebView loadRequest:request];

在加载完成中调用打印方法

- (void)webViewDidFinishLoad:(UIWebView *)webView{
    [self printWebViewPage];
}

- (void)printWebViewPage{

    UIPrintInteractionController *controller = [UIPrintInteractionController sharedPrintController];

    void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) =

    ^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {

        if(error){
            NSLog(@"FAILED! due to error in domain %@ with error code %ld-- %@",

                  error.domain, (long)error.code, completionHandler);
        }
    };

    UIPrintInfo *printInfo = [UIPrintInfo printInfo];

    printInfo.outputType = UIPrintInfoOutputGeneral;

    printInfo.jobName = @"Print for xiaodui";;

    printInfo.duplex = UIPrintInfoDuplexLongEdge;

    controller.printInfo = printInfo;

    controller.showsPageRange = YES;

   
    UIViewPrintFormatter *viewFormatter = [self.printWebView viewPrintFormatter];

    viewFormatter.startPage = 0;

    controller.printFormatter = viewFormatter;
    
    [controller presentAnimated:YES completionHandler:^(UIPrintInteractionController * _Nonnull printInteractionController, BOOL completed, NSError * _Nullable error) {

        if (!completed && error) {
            NSLog(@"Error");
        }
    }];
}
