下面的打印方法需要下载引用Spire.Presentation.dll

using Spire.Presentation;
using Spire.Presentation.Converter.Export;
using System.Drawing.Printing;

namespace PrintPPT
{
    class Program
    {
        static void Main(string[] args)
        {
            //加载需打印的PPT文档
            Presentation ppt = new Presentation();
            ppt.LoadFromFile("print.pptx");

            //初始化PresentationPrintDocument对象，用于打印设置
            PresentationPrintDocument document = new PresentationPrintDocument(ppt);

            //指定打印机
            document.PrinterSettings.PrinterName = "HP LaserJet P1007";

            //设置打印页码范围
            document.PrinterSettings.PrintRange = PrintRange.SomePages;
            document.PrinterSettings.FromPage = 1;
            document.PrinterSettings.ToPage = 2;

            //设置打印份数
            document.PrinterSettings.Copies = 1;

            //执行打印
            ppt.Print(document);
        }
    }
}
