C#调用打印机实现打印
一、引用BarcodeStandard.dll
#region BarcodeStandard.dll
/*
*
* 使用说明
需要通过NuGet进行安装BarcodeLib.dll,必不可少
*/
string inputString;
///
/// 获取所以打印机驱动名称
///
private void getPrintDocumentlist()
{
PrintDocument print = new PrintDocument();
string sDefault = print.PrinterSettings.PrinterName;//默认打印机名
comboBox_drive.Items.Add(sDefault);
comboBox_drive.Text = sDefault;//显示默认驱动名称
foreach (string sPrint in PrinterSettings.InstalledPrinters)//获取所有打印机名称
{
if (sPrint != sDefault)
{
comboBox_drive.Items.Add(sPrint);
}
}
}
///
/// 打印绘制
///
///
///
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
{
Font titleFont = new Font("宋体", 9, FontStyle.Bold);//标题字体
Font fntTxt = new Font("宋体", 9, FontStyle.Regular);//正文文字
Brush brush = new SolidBrush(Color.Black);//画刷
Pen pen = new Pen(Color.Black); //线条颜色
Point po = new Point(10, 10);
try
{
//画String
e.Graphics.DrawString(GetPrintSW().ToString(), titleFont, brush, po);//打印内容
//画横线
//Point[] point = { new Point(20, 50), new Point(200, 50) };//纵坐标不变
//e.Graphics.DrawLines(pen, point);
//画竖线
//Point[] points1 = { new Point(60, 70), new Point(60, 70 + 40) };//横坐标不变
//e.Graphics.DrawLines(pen, points1);
//画矩形
//e.Graphics.DrawRectangle(pen, 20, 70, 90, 90);
}
catch (Exception ex)
{
MessageBox.Show(this, "打印出错！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
///
/// 获取打印内容

/// 生成条形码

/// 二、引用Seagull.BarTender.Print.dll
#region Seagull.BarTender.Print.dll
///
/// 打印测试

///
///
private void printbt_Click(object sender, EventArgs e)
{
string qd = comboBox_drive.Text;//下拉列表选择的驱动名称

printDocument.PrintPage += new PrintPageEventHandler(printDocument1_PrintPage);
try
{

//PrintPreviewDialog ppd = new PrintPreviewDialog();
//ppd.Document = printDocument;
//ppd.ShowDialog();
//打印
printDocument.Print();
}
catch (InvalidPrinterException)
{
}
finally
{
printDocument.Dispose();
}
}
///
/// BarTender打印

///
///
private void BarTender_Click(object sender, EventArgs e)
{
try
{
//程序中写入引用 using Seagull.BarTender.Print.dll,必不可少;
//安装Bartender后，在安装的根目录或者system32下课可找到对应的dll
#region
Engine btEngine = new Engine();
btEngine.Start();
string lj = AppDomain.CurrentDomain.BaseDirectory + "test.btw"; //test.btw是BT的模板
LabelFormatDocument btFormat = btEngine.Documents.Open(lj);
//对BTW模版相应字段进行赋值
btFormat.SubStrings["name"].Value ="Liming";
btFormat.SubStrings["code"].Value = "1234567890";
//指定打印机名
btFormat.PrintSetup.PrinterName = "WPS 虚拟打印机";
//改变标签打印数份连载
btFormat.PrintSetup.NumberOfSerializedLabels = 1;
//打印份数
btFormat.PrintSetup.IdenticalCopiesOfLabel = 1;
Messages messages;
int waitout = 10000; // 10秒 超时
Result nResult1 = btFormat.Print("标签打印软件", waitout, out messages);
btFormat.PrintSetup.Cache.FlushInterval = CacheFlushInterval.PerSession;
//不保存对打开模板的修改
btFormat.Close(Seagull.BarTender.Print.SaveOptions.DoNotSaveChanges);
//结束打印引擎
btEngine.Stop();
#endregion
}
catch (Exception ex)
{
MessageBox.Show("错误信息: " + ex.Message);
return;
}
}
#endregion三、引用 Interop.LabelManager2.dll
#region Interop.LabelManager2.dll
