你是不是自己写一个打印类来操作的？若果是的话就看一下这个打印类（网上找的，我们老师讲过）：using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using System.Drawing.Printing;
using System.Windows.Forms;

namespace zilvhui
{
class daying
{

private DataGridView[] dataGridView;

private PrintDocument printDocument;

private PageSetupDialog pageSetupDialog;

private PrintPreviewDialog printPreviewDialog;

private int dgvIndex = 0;

private int rowCount = 0;

private int colCount = 0;

private int x = 0;

private int y = 0;

int i = 0;

private int rowGap = 30;

private int leftMargin = 40;

private Font font = new Font("Arial", 10);

private Font headingFont = new Font("Arial", 11, FontStyle.Underline);

private Font captionFont = new Font("Arial", 10, FontStyle.Bold);

private Brush brush = new SolidBrush(Color.Black);

private string cellValue = "";

bool needHeader = true;

public daying(DataGridView[] dataGridView)
{

this.dataGridView = dataGridView;

printDocument = new PrintDocument();

printDocument.PrintPage += new PrintPageEventHandler(this.printDocument_PrintPage);

}

private void printDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
dgvIndex =0;
y = 0;

for (; dgvIndex < dataGridView.Length; dgvIndex++)
{
rowCount = dataGridView[dgvIndex].Rows.Count - 1;
colCount = dataGridView[dgvIndex].ColumnCount;
//print headings
if (needHeader)
{
y += rowGap;
x = leftMargin;

for (int j = 2; j < colCount; j++)
{
if (dataGridView[dgvIndex].Columns[j].Width > 0)
{
cellValue = dataGridView[dgvIndex].Columns[j].HeaderText;
e.Graphics.FillRectangle(new SolidBrush(Color.LightGray), x, y, dataGridView[dgvIndex].Columns[j].Width, rowGap);
e.Graphics.DrawRectangle(Pens.Black, x, y, dataGridView[dgvIndex].Columns[j].Width, rowGap);
e.Graphics.DrawString(cellValue, headingFont, brush, x, y);
x += dataGridView[dgvIndex].Columns[j].Width;
}
}
}
//print all rows
for (; i < rowCount; i++)
{
y += rowGap;
if (y >= e.PageBounds.Height - 80)
{
//允许多页打印
y = 0;
e.HasMorePages = true;
i++;
needHeader = false;
return;
}

x = leftMargin;
for (int j = 2; j < colCount; j++)
{
if (dataGridView[dgvIndex].Columns[j].Width > 0)
{
cellValue = dataGridView[dgvIndex].Rows[i].Cells[j].Value.ToString();
e.Graphics.DrawRectangle(Pens.Black, x, y, dataGridView[dgvIndex].Columns[j].Width, rowGap);
e.Graphics.DrawString(cellValue, font, brush, x, y);
x += dataGridView[dgvIndex].Columns[j].Width;
}
}

}

//y += rowGap;

//for (int j = 0; j < colCount; j++)
//{
// e.Graphics.DrawString(" ", font, brush, x, y);
//}

i = 0;
}
needHeader = true;
e.HasMorePages = false;
}

public PrintDocument GetPrintDocument()
{
return printDocument;
}

public void Print()
{
try
{
pageSetupDialog = new PageSetupDialog();
pageSetupDialog.Document = printDocument;
pageSetupDialog.ShowDialog();
printPreviewDialog = new PrintPreviewDialog();
printPreviewDialog.Document = printDocument;
printPreviewDialog.Height = 600;
printPreviewDialog.Width = 800;
printPreviewDialog.ShowDialog();
}
catch (Exception e)
{
throw new Exception("Printer error." + e.Message);
}
}
}

}
//打印按钮的事件
DataGridView[] dg = { dataGridView2 };
//DataGridViewPrint dgp = new DataGridViewPrint(dg);
daying dy = new daying(dg);
dy.Print();
若果想方便一点，你可以使用水晶报表的类：这个比较方便。详细方法可以上网搜索一下。祝你成功！
