我写了一个打印机程序，可是，一点击打印的时候，第一页打印完，它打了两个空页才打印第二页，这是怎么回事， 我的代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Printing;
using Cstool;
using JohnsonI.BLL;
using JohnsonI.Model;
namespace Print_EPSON {
public partial class Print : Form
{
private T_PLAN_AUTO _model_plan_auto = new T_PLAN_AUTO();
private BLL_PLAN_AUTO _bll_plan_auto = new BLL_PLAN_AUTO();
private int _count = 0;
public Print()
{
InitializeComponent();
}
private void SetValue()
{
DataSet ds = new DataSet();
ds = _bll_plan_auto.EPSON_GET_CONFIG(); dataGridView1.DataSource = ds.Tables[0];
dataGridView1.Columns[3].Width = 150; dataGridView1.Columns[4].Width = 150;
dataGridView1.Columns[5].Width = 150;
}
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e) {
Font font;
string str;
float xPos; //x点坐标
float yPos; //y点的坐标
float topMargin = 40;
float leftMargin = 10;
DataSet ds = new DataSet();
ds = _bll_plan_auto.EPSON_GET_CONFIG();
for (int i = _count+1; i <= ds.Tables[0].Rows.Count; i++)
{
font = new Font("宋体", 12);
str = ds.Tables[0].Rows[i-1][0].ToString();
xPos = leftMargin + 15;
yPos = topMargin * i + 30;
e.Graphics.DrawString(str, font, Brushes.Black, xPos, yPos, new StringFormat());
font = new Font("宋体", 12);
str = ds.Tables[0].Rows[i-1][1].ToString();

_count = _count + 1;
//if(_count==10)
if (_count % 10==0)
{
//WritePrinter(PrinterHandle,Pinter('#12'),Len('#12')); e.HasMorePages = true;
break;
}
else if (_count == ds.Tables[0].Rows.Count)
{
e.HasMorePages = false;
_count = 0;
return;
}
}
}

你看看打印设置里的宽度或高度太小
都设置好了，我在想，怎样用程序在设置一下！我今天问售后，他说在程序里也得控制一下
