使用 Visual Basic (MS Access 2000) 将原始数据发送到 ZPL 打印机

Question

这就是我能找到的所有东西，它们都不起作用。

选项比较数据库 显式选项

  Private Type DOCINFO
      pDocName As String
      pOutputFile As String
      pDatatype As String
  End Type

  Private Declare Function ClosePrinter Lib "winspool.drv" (ByVal _

      Dim sWrittenData As String
      Dim MyDocInfo As DOCINFO
      lReturn = OpenPrinter("ZDesigner LP 2844", lhPrinter, 0)
      If lReturn = 0 Then
          MsgBox "The Printer Name you typed wasn't recognized."
          Exit Sub
      End If
      MyDocInfo.pDocName = "AAAAAA"
      MyDocInfo.pOutputFile = vbNullString
      MyDocInfo.pDatatype = vbNullString
      lDoc = StartDocPrinter(lhPrinter, 1, MyDocInfo)
      Call StartPagePrinter(lhPrinter)
       sWrittenData = "N" & vbFormFeed
      sWrittenData = sWrittenData & "q609" & vbFormFeed
      sWrittenData = sWrittenData & "Q203,26" & vbFormFeed
      sWrittenData = sWrittenData & "B26,26,0,UA0,2,2,152,B," & Chr(34) & "603679025109" & Chr(34) & vbFormFeed
      sWrittenData = sWrittenData & "A253,26,0,3,1,1,N," & Chr(34) & "SKU 6205518 MFG 6354" & Chr(34) & vbFormFeed
      sWrittenData = sWrittenData & "A253,56,0,3,1,1,N," & Chr(34) & "2XIST TROPICAL BEACH" & Chr(34) & vbFormFeed
      sWrittenData = sWrittenData & "A253,86,0,3,1,1,N," & Chr(34) & "STRIPE SQUARE CUT TRUNK" & Chr(34) & vbFormFeed
      sWrittenData = sWrittenData & "A253,116,0,3,1,1,N," & Chr(34) & "BRICK" & Chr(34) & vbFormFeed
      sWrittenData = sWrittenData & "A253,146,0,3,1,1,N," & Chr(34) & "X-LARGE" & Chr(34) & vbFormFeed
      sWrittenData = sWrittenData & "P1,1" & vbFormFeed
      lReturn = WritePrinter(lhPrinter, ByVal sWrittenData, _
         Len(sWrittenData), lpcWritten)
      lReturn = EndPagePrinter(lhPrinter)
      lReturn = EndDocPrinter(lhPrinter)
      lReturn = ClosePrinter(lhPrinter)
  End Sub

方法二

Option Compare Database

Private Sub crtLabel()


Dim prtDevice As String
Dim strQuote As String

strQuote = Chr(34)
prtDevice = "ZDesigner LP 2844" ' whatever device Access currently has as the default. I have the user select a printer prior to printing, which sets the Access defaut printer

' open printer port
Open prtDevice For Output As #1
' initialize printer
Print #1, "OD" & vbCrLf
Print #1, "N" & vbCrLf
Print #1, "O" & vbCrLf
Print #1, "Q545,B12+23" & vbCrLf
Print #1, "q262" & vbCrLf
Print #1, "UN" & vbCrLf
Print #1, "rN" & vbCrLf
Print #1, "N" & vbCrLf
Print #1, "A4,94,3,3,1,1,N," & strQuote & "1803" & strQuote & vbCrLf
Print #1, "A36,74,3,3,1,1,N," & strQuote & "B" & strQuote & vbCrLf
Print #1, "A64,94,3,3,1,1,N," & strQuote & "079" & strQuote & vbCrLf
Print #1, "A112,8,0,2,1,1,N," & strQuote & strQuote & vbCrLf ' you can replace any string like "1803" with a string variable like SID or AID that gets passed to the sub
Print #1, "A112,32,0,3,1,1,N," & strQuote & strQuote & vbCrLf  ' same here
Print #1, "A112,64,0,1,1,1,N," & strQuote & "04/13/2009" & strQuote & vbCrLf
Print #1, "A130,100,0,1,1,1,N," & strQuote & "SWAB, NASO" & strQuote & vbCrLf
Print #1, "A4,100,0,1,1,1,N," & strQuote & "C146536" & strQuote & vbCrLf
Print #1, "B53,130,0,1,1,0,47,N," & strQuote & "2009-06868" & strQuote & vbCrLf
Print #1, "A112,188,0,1,1,1,N," & strQuote & "" & strQuote & vbCrLf
Print #1, "P1,1" & vbCrLf
Print #1, "O" & vbCrLf
' close printer port
Close #1


End Sub

运行函数后没有任何反应。就像打印机根本没有被代码触及一样。

更新 方法 1 是最接近打印文件的方法。执行命令后，状态栏有一个打印机图标显示打印机已被调用并从我的代码接收数据，但仍然没有打印。帮助...

Answer 1

如果它映射到并行或com端口，您可以直接打开它：

open "LPT1:" For Output as #1
' or open "COM1:"
print #1, "SomeData"
Close #1

Answer 2

我喜欢做的事情类似于您的方法 2，但将其保存到文件（原始打印机数据），然后将文件复制到 UNC 路径。

文件复制“C:\label.txt”\computername\sharename

这对我有用。

Answer 3

好的，这就是我设法让事情发挥作用的方法。不是我想要的最佳选择，但......它有效。

1) 我使用相同的函数，但用 C++ 编写，取自这里http://support.microsoft.com/kb/138594/EN-US

// RawDataToPrinter - sends binary data directly to a printer
   // 
   // Params:
   //   szPrinterName - NULL terminated string specifying printer name
   //   lpData        - Pointer to raw data bytes
   //   dwCount       - Length of lpData in bytes
   // 
   // Returns: TRUE for success, FALSE for failure.
   // 
   BOOL RawDataToPrinter(LPSTR szPrinterName, LPBYTE lpData, DWORD dwCount)
   {
     HANDLE     hPrinter;
     DOC_INFO_1 DocInfo;
     DWORD      dwJob;
     DWORD      dwBytesWritten;

     // Need a handle to the printer.
     if( ! OpenPrinter( szPrinterName, &hPrinter, NULL ) )
       return FALSE;

     // Fill in the structure with info about this "document."
     DocInfo.pDocName = "My Document";
     DocInfo.pOutputFile = NULL;
     DocInfo.pDatatype = "RAW";
     // Inform the spooler the document is beginning.
     if( (dwJob = StartDocPrinter( hPrinter, 1, (LPSTR)&DocInfo )) == 0 )
     {
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // Start a page.
     if( ! StartPagePrinter( hPrinter ) )
     {
       EndDocPrinter( hPrinter );
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // Send the data to the printer.
     if( ! WritePrinter( hPrinter, lpData, dwCount, &dwBytesWritten ) )
     {
       EndPagePrinter( hPrinter );
       EndDocPrinter( hPrinter );
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // End the page.
     if( ! EndPagePrinter( hPrinter ) )
     {
       EndDocPrinter( hPrinter );
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // Inform the spooler that the document is ending.
     if( ! EndDocPrinter( hPrinter ) )
     {
       ClosePrinter( hPrinter );
       return FALSE;
     }
     // Tidy up the printer handle.
     ClosePrinter( hPrinter );
     // Check to see if correct number of bytes were written.
     if( dwBytesWritten != dwCount )
       return FALSE;
     return TRUE;
   }

我从那里得到文件 RAWPRN.EXE，将我的 EPL 代码放在一个 txt 文件中。最后用Shell来执行

Dim RetVal
RetVal = Shell("cmd .exe /c C:\rawprint\RawPrint.exe ""ZDesigner LP 2844"" ""C:\eplcode.txt""", 1)

Answer 4

我的 Zebra 解决方案

1. 在 Windows 中创建通用/文本打印机，然后将原始文件发送到此打印机
2. 在 Zebra 打印机高级设置 --> 其他中， 有一个直通字符。您可以将原始文本连同它一起发送到这台打印机。
