两种打印方式：机器码打印、调用CodeSoft.
调用CodeSoft打印：
利用第三方软件codesofe进行label设计，然后在程序中调用打印。
这种方式维护起来比较方便，手动调整label各参数指标即可。
准备工作：
1.安装打印机驱动
2.安装codeSoft
3.设计label,设置label参数
程序实现：
注意首先添加引用：Lppx2.tlb （codesoft安装后文件中）
using LabelManager2; //引入命名空间
private void btnPrint_Click(object sender, EventArgs e)
{
ApplicationClass lbl = new ApplicationClass();
try
{
lbl.Documents.Open(@"D:label.Lab", false);// 调用设计好的label文件
Document doc = lbl.ActiveDocument;
doc.Variables.FormVariables.Item("Var0").Value = txtContent.Text.Trim(); //给参数传值
doc.Variables.FormVariables.Item("Var1").Value = txtContent2.Text.Trim(); //给参数传值
int Num = Convert.ToInt32(txtQuentity.Text); //打印数量
doc.PrintDocument(Num); //打印
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
lbl.Quit(); //退出
}
} 机器码打印：
这种方式直接使用打印机机器指令进行打印，调用系统接口函数实现。
1.建立接口函数类 LPTControl
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace SMTOffLine
{
class LPTControl
{
[StructLayout(LayoutKind.Sequential)]
private struct OVERLAPPED
{
int Internal;
int InternalHigh;
int Offset;
int OffSetHigh;
int hEvent;
}
[DllImport("kernel32.dll")]
private static extern int CreateFile(
string lpFileName,
uint dwDesiredAccess,
int dwShareMode,
int lpSecurityAttributes,
int dwCreationDisposition,
int dwFlagsAndAttributes,
int hTemplateFile
);
[DllImport("kernel32.dll")]
private static extern bool WriteFile(
int hFile,
byte[] lpBuffer,
int nNumberOfBytesToWrite,
out int lpNumberOfBytesWritten,
out OVERLAPPED lpOverlapped
);
[DllImport("kernel32.dll")]
private static extern bool CloseHandle(
int hObject
);
private int iHandle;
public bool Open()
{
iHandle = CreateFile("lpt1", 0x40000000, 0, 0, 3, 0, 0);
if (iHandle != -1)
{
return true;
}
else
{
return false;
}
}
public bool Write(String Mystring)
{
if (iHandle != -1)
{
int i;
OVERLAPPED x;
byte[] mybyte = System.Text.Encoding.Default.GetBytes(Mystring);
return WriteFile(iHandle, mybyte, mybyte.Length, out i, out x);
}
else
{
throw new Exception("打印機端口未打開!");
}
}
public bool Close()
{
return CloseHandle(iHandle);
}
}
}
2.程序实现
private void btnPrint_Click(object sender, EventArgs e)
{
string PtrStr = "";
string MaterialNo="";
string StartValue="";
int PrintNum ;
LPTControl Print = new LPTControl();
try
{
Print.Open();
for (int i = 0; i < dtPrint.Rows.Count; i++)
{
MaterialNo = dtPrint.Rows[i][0].ToString();
StartValue = dtPrint.Rows[i][1].ToString();
PrintNum = Convert.ToInt32(numericUpDown1.Value);
for (int j = 0; j < PrintNum; j++)
{
int FlowNo =(Convert.ToInt32(StartValue) + j+1);
string StrFlowNo = FlowNo.ToString("000000");
PtrStr = "";
PtrStr += "^XA^LH40,20";
PtrStr += "^FO10,10^BY3,2,90^B3,N,90,N,N^FD" + MaterialNo + "^FS";
PtrStr += "^FO10,105^AE^FD" + MaterialNo + "^FS";
PtrStr += "^FO10,145^BY3,2,90^B3,N,90,N,N^FD" + StrFlowNo + "^FS";
PtrStr += "^FO10,245^AE^FD" + StrFlowNo + "^FS";
PtrStr += "^FO10,280^BY3,2,90^B3,N,90,N,N^FD" + DateTime.Now.ToString("yyyy-MM-dd") + "^FS";
PtrStr += "^FO10,385^AE^FD" + DateTime.Now.ToString("yyyy-MM-dd") + "^FS";
PtrStr += "^XZ";
Print.Write(PtrStr);
}
//update newest Num to DB
int NewNum = Convert.ToInt32(StartValue) +PrintNum;
string SqlUpdate = "update tablelabel set curren_value=" + NewNum + " where material_id='" + MaterialNo + "'";
try
{
DAL DbOp = new DAL();
DbOp.ExecDBOp(SqlUpdate);
}
catch (Exception ex)
{
MessageBox.Show("Error","information");
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Information");
}
finally
{
Print.Close();
}
}
