C#中使用GDI+实现复杂打印
if( a != null )
{
a.Clear();
}
for( int m = 0; m < 3; m ++ )
{
ArrayList a1 = new ArrayList();
string x0 = "住院患者一日清单";
string x1 = "入院日期：2007-11-11 结算日期：2007-11-11 至 2007-11-15 ";
string x2 = "姓名：欧阳峰 住院号：20090909090 床：512 妇科";
string x3 = "项目编号*项目名称*单价*数量*单位"; // 注意其中的*标志
string[] x4 = new string[ 90 ]; // 假设有90条数据，不固定
for( int i = 0; i < 90; i ++ )
{
x4[ i ] = "juejue1984*www.loyosoft.com*11.00*11*鸟"; // 注意其中的*标志
}
string x5 = "费用累计：2500*小计：400 ";
string x6 = "累计按金：3600*余额：1600 ";
string x7 = "”;
string x8 = "”;
a1.Add( x0 );
a1.Add( x1 );
a1.Add( x2 );
a1.Add( x3 );
a1.Add( x4 );
a1.Add( x5 );
a1.Add( x6 );
a1.Add( x7 );
a1.Add( x8 );
a. Add( a1 );
然后在PrintDocument对象的PrinPage事件作如下处理：
Size sTotal = new Size( 420, e.PageBounds.Height );
Graphics g = e.Graphics;
Font fTitle = new Font( "宋体", 16 ); // 标题字体
int titleHeight = 20; // 标题的高度
int textHeight = 13; // 普通文本的高度
Font fText = new Font( "宋体", 9 ); // 文本字体
int top = 30; // 顶部间距
int left = 10; // 左边距
int right = 10; // 右边距
int titleMargin = 15; // 标题和正文行间距
int textMargin = 5; // 行间距
int rectangleMargin = 3; // 边框和文本间距
int oneHeight = 19; // 一行文本 + 2 * 行间距的高度
int oneWidth = sTotal.Width - left - right; // 打印内容的宽度
int y = 0;
while ( j < a.Count ) // Count为要打印的患者个数
{
ArrayList a3 = a[ j ] as ArrayList; // a3位要打印的患者的清单内容。
if( y >= e.PageBounds.Height - titleHeight ) // 如果已经到了底部则开始下一页
{
e.HasMorePages = true;
return;
}
//
string x = a3[ 0 ] as string;
if( !this.JudgeString( x ) ) // 如果此行记录还未打印过
{
//string x = "住院患者一日清单"; // a1
SizeF sTitle = g.MeasureString( x, fTitle ); // 计算标题的长度和高度
Point pTitle = new Point( ( sTotal.Width - (int)sTitle.Width ) / 2, y + top ); // 使标题绝对居中
y += top; // 1
//
g.DrawString( x, fTitle, Brushes.Black, pTitle.X, y ); // 标题
this.AddPrintedSign( ref x );
a3[ 0 ] = x; // 标记该患者的此行内容为已经打印过
y += titleHeight + titleMargin; // Y坐标下移
}
//
if( y >= e.PageBounds.Height - oneHeight )
{
e.HasMorePages = true;
return;
}
//// 正文第一行

{

this.AddPrintedSign( ref r1 );

//
