打印多张分页图片工具类

 工具类创建，可以直接复制粘贴

    /// <summary>
    /// 获取图片打印图片
    /// </summary>
    public class PrintImage
    {
        PrintDocument _document = new PrintDocument();

        public PrintDocument Document
        {
            get { return _document; }
            set { _document = value; }
        }
        List<Image> _lstImage = new List<Image>();
        /// <summary>
        /// 普通集合
        /// </summary>
        public List<Image> LstImage
        {
            get { return _lstImage; }
            set { _lstImage = value; }
        }
        /// <summary>
        /// 设置双面打印
        /// </summary>
        public Duplex Duplex
        {
            set
            {
                if (this.Document != null)
                    Document.PrinterSettings.Duplex = value;
            }
            get
            {
                if (this.Document != null)
                    return Document.PrinterSettings.Duplex;
                return default(Duplex);
            }
        }


        public PrintImage()
        {
            _document.PrintPage += new PrintPageEventHandler(_document_PrintPage);
        }
        /// <summary>
        /// 
        /// </summary>
        /// <param name="imgs"></param>
        public void LoadData(params Image[] imgs)
        {
            foreach (var item in imgs)
            {
                _lstImage.Add(item);
            }
        }

        int _pageNum = 1;//初始页面数
        void _document_PrintPage(object sender, PrintPageEventArgs e)
        {
            var item = _lstImage[_pageNum - 1];
            Rectangle destRect = new Rectangle(0, 100, item.Width, item.Height);
            e.Graphics.DrawImage(item, destRect, 0, 0, item.Width, item.Height, System.Drawing.GraphicsUnit.Pixel);

            if (_pageNum < _lstImage.Count)
            {
                e.HasMorePages = true;//每张图片都换页打印
                _pageNum++;
            }
        }
        /// <summary>
        /// 打印
        /// </summary>
        public void Print()
        {
            Document.Print();
        }
    }

 调用类的方式：

        //调用方式
        public static void Test()
        {
            PrintImage printImage = new PrintImage();
            printImage.Duplex = Duplex.Vertical;//双面打印设置
            var img1 = Image.FromFile("1.jpg");
            var img2 = Image.FromFile("2.jpg");
            printImage.LoadData(img1, img2);//增加两张图片
            printImage.Print();//直接打印
        }

PrintDocument双面打印打印，每张图片都是分页打印。
