winform 打印条码
2024-09-30 19:10:37
一个winform打印功能的示例
操作步骤：
1、新建winform项目及创建窗体
2、拖取 打印 相关控件
PageSetupDialog 、 PrintDialog 、 PrintDocument 、PrintPreviewDialog
3、设置上述控件的Document属性为相应的PrintDocument
4、设置按钮等控件 及 添加相应按钮事件
public partial class Form3 : Form
{
public Form3()
{
InitializeComponent();
this.printDocument1.OriginAtMargins = true;//启用页边距
this.pageSetupDialog1.EnableMetric = true; //以毫米为单位 } //打印设置
private void btnSetPrint_Click(object sender, EventArgs e)
{
this.pageSetupDialog1.ShowDialog();
} //打印预览
private void btnPrePrint_Click(object sender, EventArgs e)
{
this.printPreviewDialog1.ShowDialog();
} //打印
private void btnPrint_Click(object sender, EventArgs e)
{
if (this.printDialog1.ShowDialog() == DialogResult.OK)
{
this.printDocument1.Print();
}
} //打印内容的设置
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
////打印内容 为 整个Form
//Image myFormImage;
//myFormImage = new Bitmap(this.Width, this.Height);
//Graphics g = Graphics.FromImage(myFormImage);
//g.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);
//e.Graphics.DrawImage(myFormImage, 0, 0); ////打印内容 为 局部的 this.groupBox1
//Bitmap _NewBitmap = new Bitmap(groupBox1.Width, groupBox1.Height);
//groupBox1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));
//e.Graphics.DrawImage(_NewBitmap, 0, 0, _NewBitmap.Width, _NewBitmap.Height); //打印内容 为 自定义文本内容
Font font = new Font("宋体", );
Brush bru = Brushes.Blue;
for (int i = ; i <= ; i++)
{
e.Graphics.DrawString("Hello world ", font, bru, i*, i*);
}
}
}
