在打印时怎样在代码中设置纸张大小和页边距,是c#中的winform程序

Answer 1

打印 用到 PrintDocument这个类。可以通过它的属性控制 你需要的
public class PrintingExample : System.Windows.Forms.Form
{
private System.ComponentModel.Container components;
private System.Windows.Forms.Button printButton;
private Font printFont;
private StreamReader streamToPrint;

public PrintingExample() : base()
{
// The Windows Forms Designer requires the following call.
InitializeComponent();
}

// The Click event is raised when the user clicks the Print button.
private void printButton_Click(object sender, EventArgs e)
{
try
{
streamToPrint = new StreamReader
("C:\\My Documents\\MyFile.txt");
try
{
printFont = new Font("Arial", 10);
PrintDocument pd = new PrintDocument();
pd.PrintPage += new PrintPageEventHandler
(this.pd_PrintPage);
pd.Print();
}
finally
{
streamToPrint.Close();
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}

// The PrintPage event is raised for each page to be printed.
private void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
float linesPerPage = 0;
float yPos = 0;
int count = 0;
float leftMargin = ev.MarginBounds.Left;
float topMargin = ev.MarginBounds.Top;
string line = null;

// Calculate the number of lines per page.
linesPerPage = ev.MarginBounds.Height /
printFont.GetHeight(ev.Graphics);

// Print each line of the file.
while(count < linesPerPage &&
((line=streamToPrint.ReadLine()) != null))
{
yPos = topMargin + (count *
printFont.GetHeight(ev.Graphics));
ev.Graphics.DrawString(line, printFont, Brushes.Black,
leftMargin, yPos, new StringFormat());
count++;
}

// If more lines exist, print another page.
if(line != null)
ev.HasMorePages = true;
else
ev.HasMorePages = false;
}

// The Windows Forms Designer requires the following procedure.
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
this.printButton = new System.Windows.Forms.Button();

this.ClientSize = new System.Drawing.Size(504, 381);
this.Text = "Print Example";

printButton.ImageAlign =
System.Drawing.ContentAlignment.MiddleLeft;
printButton.Location = new System.Drawing.Point(32, 110);
printButton.FlatStyle = System.Windows.Forms.FlatStyle.Flat;
printButton.TabIndex = 0;
printButton.Text = "Print the file.";
printButton.Size = new System.Drawing.Size(136, 40);
printButton.Click += new System.EventHandler(printButton_Click);

this.Controls.Add(printButton);
}

// This is the main entry point for the application.
public static void Main(string[] args)
{
Application.Run(new PrintingExample());
}
}

你用的是什么报表,如果是水晶报表的话:
在报表上空白处右键->设计器->打印机设置和页面设置里分别有你要的内容
