同为网上找来的 看是否有用
//以表格形式打印DataTable内容
//定义全局变量count，储存当前打印的行数
int count=0;
//定义一个方法，接收一个DataTable类型参数及PrintDocument的PrintPage事件传入的参数e以方便操作
private void PrintTable(DataTable dt, System.Drawing.Printing.PrintPageEventArgse)
{
//取得对应的Graphics对象
Graphicsg = e.Graphics;
//获得相关页面X坐标、Y坐标、打印区域宽度、长度
intx = e.PageSettings.Margins.Left;
inty = e.PageSettings.Margins.Top;
intwidth = e.PageSettings.PaperSize.Width -e.PageSettings.Margins.Left- e.PageSettings.Margins.Right;
intheight = e.PageSettings.PaperSize.Height -e.PageSettings.Margins.Top -e.PageSettings.Margins.Bottom;
//定义打印字体
Fontfont = new Font("宋体",15);
//rowCount是除去打印过的行数后剩下的行数
introwCount = dt.Rows.Count-count;
//maxPageRow是当前设置下该页面可以打印的最大行数
intmaxPageRow=height/(int)font.GetHeight();
//因为是表格，先画一条水平直线
g.DrawLine(newPen(Brushes.Black, 1), new Point(x, y), new Point(x +(dt.Columns.Count) * 135, y));
//再画出表格各列的列标题
for(int i = 0; i < dt.Columns.Count; i++)
{
stringhead = dt.Columns[i].ColumnName;
g.DrawString(head,font, Brushes.Black, x + i * 135, y);
}
//画完标题，再画一条直线
g.DrawLine(newPen(Brushes.Black, 1), new Point(x, y + (int)font.GetHeight()), newPoint(x + (dt.Columns.Count) * 135, y +(int)font.GetHeight()));
//判断，如果剩下的行数小于可打印的最大行数，则执行下列代码
if(maxPageRow >=rowCount)
{
//当前行数小于Table内总行数时，循环
while(count < dt.Rows.Count)
{
//内循环打印Table内行数据
intcolumnCount = 0;
while(columnCount < dt.Columns.Count)
{
stringtemp = dt.Rows[count][columnCount].ToString();
//打印每个单元格内的数据
g.DrawString(temp,font, Brushes.Black, x + columnCount * 135, y + (count %maxPageRow) * (int)font.GetHeight() +(int)font.GetHeight());
//打印完一行后，继续打印一条直线
g.DrawLine(newPen(Brushes.Black, 1), new Point(x, y + (count % maxPageRow) *(int)font.GetHeight() + 2 * (int)font.GetHeight()), new Point(x +(dt.Columns.Count) * 135, y + (count % maxPageRow) *(int)font.GetHeight() + 2 * (int)font.GetHeight()));
columnCount++;
}
count++;
}
//所有数据打印完毕后，打印垂直直线
for (int i = 0; i <= dt.Columns.Count; i++)
{
g.DrawLine(newPen(Brushes.Black), new Point(x + i * 135, y), new Point(x + i *135, y + rowCount * (int)font.GetHeight() +(int)font.GetHeight()));
}
}
//判断，如果剩下的行数大于可打印的最大行数，则执行下列代码
else
{
do
{
//与上面类似，注意下面while的条件
intcolumnCount = 0;
while(columnCount < dt.Columns.Count)
{
stringtemp = dt.Rows[count][columnCount].ToString();
//打印每个单元格
g.DrawString(temp,font, Brushes.Black, x + columnCount * 135, y + (count %maxPageRow) * (int)font.GetHeight() +(int)font.GetHeight());
//打印水平直线
g.DrawLine(newPen(Brushes.Black, 1), new Point(x, y + (count % maxPageRow) *(int)font.GetHeight() + 2 * (int)font.GetHeight()), new Point(x +(dt.Columns.Count)*135, y + (count % maxPageRow) *(int)font.GetHeight() + 2 * (int)font.GetHeight()));
columnCount++;
}
count++;
}while ((count % maxPageRow >0));
//打印垂直直线
for(int i = 0; i <= dt.Columns.Count;i++ )
{
g.DrawLine(newPen(Brushes.Black), new Point(x + i * 135, y), new Point(x + i *135, y + height + (int)font.GetHeight()));
}
}
//指定HasMorePages值，如果页面最大行数小于剩下的行数，则返回true（还有），否则返回false
if(maxPageRow<rowCount)
{
e.HasMorePages= true;
}
else
{
e.HasMorePages= false;
count= 0;
}
}
//-----------------------------------------------------------------------------------------
//打印预览
private void button2_Click(object sender, EventArgs e)
{
//注意指定其Document属性
this.printPreviewDialog1.Document = this.printDocument1;
this.printPreviewDialog1.ShowDialog();
}
//打印
private void button1_Click(object sender, EventArgs e)
{
//同样注意指定Document属性
this.printDialog1.Document = this.printDocument1;
if (this.printDialog1.ShowDialog() == DialogResult.OK)
{
//触发PrintDocument的PrintPage事件
this.printDocument1.Print();
}

顶，不太清楚，但先导出再打印是绝对没有问题滴

可以利用 水晶报表 打印，方便直观。
1)dataset ds=new dataset();
再构建table tb
再把table 添加到ds中。 ds.add.tb....
2)再把 报表绑定到 ds. 就可打印了。
