PrintDocument打印、预览、打印机设置和打印属性的方法

  WindowsForm 使用 PrintDocument打印、预览、打印机设置和打印属性的方法。

private void Form1_Load(object sender, System.EventArgs e) 
{ 
//获取或设置一个值,该值指示是否发送到文件或端口 
printDocument1.PrinterSettings.PrintToFile = true; 
//设置打印时横向还是纵向 
printDocument1.DefaultPageSettings.Landscape = true; 
} 
private void fileOpenMenuItem_Click(object sender, System.EventArgs e) 
{ 
OpenFile(); 
} 
private void OpenFile() 
{ 
openFileDialog1.Filter = "Text Files (*.txt)|*.txt";//打开文本的类型 
//获取文件对话框的初始目录(StartupPath)获得bin文件下的文件 
openFileDialog1.InitialDirectory = System.Windows.Forms.Application.StartupPath; 
DialogResult userResponse = openFileDialog1.ShowDialog(); 
//MessageBox.Show(userResponse.ToString()); 
if (userResponse==DialogResult.OK) 
{ 
filePath = openFileDialog1.FileName.ToString();//转换文件路径 
} 
} 
private void MyPrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) 
//充分利用e 
{ 
int topMargin = printDocument1.DefaultPageSettings.Margins.Top;//上边距 
int leftMargin = printDocument1.DefaultPageSettings.Margins.Left;//左边距 
float linesPerPage = 0;//页面行号 
float verticalPosition = 0;//绘制字符串的纵向位置 
float horizontalPosition=leftMargin;//左边距 
string textLine = null;//行字符串 
currentLine = 0;//行计数器 
// float Xline=0; 
//int line=0; 
// Calculate the number of lines per page. 
linesPerPage = e.MarginBounds.Height / myFont.GetHeight(e.Graphics); 
// Xline=e.MarginBounds.Width/myFont.GetHeight(); 
// for each text line that will fit on the page, read a new line from the document 
while (currentLine < linesPerPage ) 
{ 
textLine = streamToPrint.ReadLine(); 
if(textLine == null) 
{ 
break; 
} 
// 求出已经打印的范围 
verticalPosition = topMargin + currentLine * myFont.GetHeight(e.Graphics); 
// 设置页面的属性 
e.Graphics.DrawString(textLine, myFont, myBrush, horizontalPosition, verticalPosition); 
// 增加行数 
currentLine ++; 
} 
// If more lines of text exist in the file, print another page.
