C# WPF 调用打印机的两种方法

最近在调试打印机，为了方便测试写了一个小demo。为了更好的判断是打印机硬件的问题还是动态库的问题，设定了定时器不间断打印来进行测试。现来分享记录一下。

需要调用两种动态库

1. PdfPrintingNet.dll动态库
2. O2S.Components.PDFRender4NET.dll and O2S.Components.PDFView4NET.dll方法引用。直接调用路径

动态库和demo都会上传到资源里，以便大家参考。

这里是用的三星打印机，各位如果需要自己装驱动。亲测可用

using PdfPrintingNet;
using System;
using System.Timers;
using System.Windows;
using System.Drawing.Printing;
using System.Diagnostics;
using System.Collections.Specialized;
using O2S.Components.PDFRender4NET;

namespace WpfApp1
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public System.Timers.Timer timer = new System.Timers.Timer();//定时器的引用
        string pathe = AppDomain.CurrentDomain.BaseDirectory + "1.pdf";//物理路径 直接到Debug下
        PdfPrint pdfprint = new PdfPrint("", "");
        public MainWindow()
        {
            InitializeComponent();
            //定时器调用循环
            timer.Interval = 1000*20;//这里设置的间隔时间为毫秒
            timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);//执行方法
            timer.AutoReset = true;//设置timer_Elapsed是执行一次（false）还是一直执行（true）
            timer.Enabled = true;
            timer.Start();

        }
        //方法一------O2S.Components.PDFRender4NET.dll  and O2S.Components.PDFView4NET.dll方法引用。直接调用路径

            //设置纸张大小（可以不设置，取默认设置）3.90 in,  8.65 in
            PaperSize ps = new PaperSize("test", 4, 9);
            ps.RawKind = 9; //如果是自定义纸张，就要大于118，（A4值为9，详细纸张类型与值的对照请看http://msdn.microsoft.com/zh-tw/library/system.drawing.printing.papersize.rawkind(v=vs.85).aspx）
