关于C#打印的问题，打印预览和实际打印结果不一样。
领导让写个打印程序，自己测试了好久，预览的效果和实际打印的效果总是有很大的差异。预览是距离打印的纸张没有什么距离
而实际打印的时候 距离纸张左侧有大概4厘米左右的距离。右侧也是一样。
求解！求帮助！
下面是跟网上找的代码改的 效果跟自己写的一样。
private void button1_Click(object sender, EventArgs e)
{
this.printDocument1.OriginAtMargins = true;
this.printDocument1.DefaultPageSettings.PaperSize =
new System.Drawing.Printing.PaperSize("Custom", PaperWidth, PaperHeight);
this.printDocument1.DefaultPageSettings.PaperSize.RawKind = 300;
this.printDocument1.DefaultPageSettings.Margins = new System.Drawing.Printing.Margins(15, 15,15,15);
this.printDocument1.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(printDocument1_PrintPage);
//将写好的格式给打印预览控件以便预览
printPreviewDialog1.Document = printDocument1;
//显示预览
DialogResult result = printPreviewDialog1.ShowDialog();
if (result == DialogResult.OK)
{
this.printDocument1.Print();
}
}

C# --------------------编程问答-------------------- 这个要看什么型号的打印机。而且不同的系统也不同。 --------------------编程问答-------------------- 实际打印：
预览：
--------------------编程问答-------------------- 我的是win7 64位系统
我在xp 32位系统上也不行
怎么能让实际打印的时候左侧，右侧不留那么大的边距呢？ --------------------编程问答--------------------
怎么能减少实际打印的时候左侧、右侧的的距离呢？ --------------------编程问答-------------------- 因为屏幕和打印机的分辨率不一样，同样的坐标表示的位置是不同的，
可以用下面的语句将坐标单位进行统一，具体用哪个单位你可以多试几下，
然后所有的坐标和尺寸要重新计算：
e.Graphics.PageUnit = GraphicsUnit.Document; --------------------编程问答--------------------
我加上这个了，但是没起作用，是加在打印事件里面么？ --------------------编程问答-------------------- this.printDocument1.DefaultPageSettings.Margins = new System.Drawing.Printing.Margins(0, 0,0,0);
试试 --------------------编程问答--------------------
这个也试过了不行 --------------------编程问答-------------------- 把页面除了margins之外的部分（内部），画成一个矩形显示在打印纸上，看上有没有偏差。
--------------------编程问答--------------------
什么打印机？这跟打印机边距有关系，要到打印机里面设一下对应参数 --------------------编程问答-------------------- TitleFormat.Alignment = StringAlignment.Center; --------------------编程问答-------------------- TitleFormat.Alignment = StringAlignment.Center; --------------------编程问答-------------------- TitleFormat.Alignment = StringAlignment.Center;？确认没有 问题？画图的代码一部分看不到，调用了吗？
补充：.NET技术 , C#
