一，通过三菱PLC连斑马打印机

1)通过RS指令发送ZPL II (zebra的编程语言)到打印机。通讯方式为RS232。

注意：RS指令要一直通电，通过脉冲触发M8122(发送请求)，就能将指令传到打印机打印。

2)在三菱的D Memoryz中写入字符(ZPL II指令)，可以用复制/粘贴TXT文档中的指令。

3)ZM400打印机的有Z/R/E存储区,分别为EPROM/DRAM/FLASH。DRAM掉电后不保持。

4)通过DF/XF存储/调用在存储区的打印格式。

二、通过VB.NET控制Zebra M400打印

三、如何将ZebraDesigner设计的标签转成为ZPL指令的.txt文档？

安装好打印机驱动，修改打印机端口，新建一个打印机端口，类型为本地端口，端口名称设置为C:\printer.log，再用标签设计软件打印一次，此文件中就有ZPL指令了。

这时碰到一个问题，就是如何将多行字符传送到RawPrinterHelper()，将字符串放入xml中，如下：

Dim strZPL =

^XA

^XFR:SAMPLE.GRF

^FN1^FD^FS      'Testbox1中的内容

^XZ

.Value

四、将电脑上的打印机名称列举出来

For Each pkInstalledPrinters As String In System.Drawing.Printing.PrinterSettings.InstalledPrinters

cmbInstalledPrinters.Items.Add(pkInstalledPrinters)

Next

If (cmbInstalledPrinters.Items.Contains("Zebra ZM400 200 dpi (ZPL)")) Then

cmbInstalledPrinters.Text = "Zebra ZM400 200 dpi (ZPL)"

End If

End If

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

RawPrinterHelper.SendStringToPrinter(cmbInstalledPrinters.Text, strZPLFormat)

End Sub

Private Sub SendFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SendFile.Click

RawPrinterHelper.SendFileToPrinter(cmbInstalledPrinters.Text, "D:\print.log")

End Sub

Dim strZPL =

^XA

^XFR:SAMPLE.GRF

.Value

If (Not String.IsNullOrEmpty(TextBox1.Text)) Then

RawPrinterHelper.SendStringToPrinter(cmbInstalledPrinters.Text, strZPL)

Else

MessageBox.Show("text is Empty")

End If

End Sub
