Send Raw Data to ZPL Printer using Visual Basic (MS Access 2000) - vba

This is all that I can find, none of them work.

Method 2

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, "P1,1" & vbCrLf
Print #1, "O" & vbCrLf
' close printer port
Close #1
End Sub
Nothing happens after running the function. It's like the printer is not touched at all by the code.
UPDATE
Method 1 is the closest thing I can get to printing the file. After executing the command, there is a printer icon at the status bar show that the printer has been called and receiving data from my code, but still, no printing at all. Help...

Answer 1

if it is mapped to a parallel or com port, you can open that directly:
open "LPT1:" For Output as #1
' or open "COM1:"
print #1, "SomeData"
Close #1

Answer 2

What I like to do is do something similar to your Method 2, but save it to a file (the raw printer data) and then do a file copy to the UNC path.
file copy "C:\label.txt" \computername\sharename
That works for me.

Answer 3

Okay so this is how I managed to get thing this work. Not a best option as I wanted but ... it works.
1) I use the same function, but written in C++, taken from here 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;
}
I got the file RAWPRN.EXE from there, put my EPL code in a txt file. Finally, use Shell to execute it
Dim RetVal
RetVal = Shell("cmd .exe /c C:\rawprint\RawPrint.exe ""ZDesigner LP 2844"" ""C:\eplcode.txt""", 1)

Answer 4

My solution for Zebra
Creating a generic/text printer in windows then sending to raw file to this printer
In Zebra printers advanced settings --> others,
there is a passthrough characters. You can send raw text with this to this printer.

Answer 5

I use this solution, works perfect.
make a generic text printer, following this recipe
Map the printer to LPT1, using "net use lpt1 \\computername\printername /persistent:yes
Send files to the printer, using:
VBA
Public function runCmd(cmd as String) as Boolean
Dim wsh As Object
Dim cmdToRun As String
Dim Sts As Integer
Set wsh = VBA.CreateObject("WScript.Shell")
cmdToRun = "cmd.exe /c " & Quote(cmd)
'Run & wait to complete
Sts = wsh.Run(cmdToRun, 0, 1)
If Sts = 0 Then
runCmd = True
Else
MsgBox cmd & vbCrLf & "Failed with error code " & Sts
End If
Set wsh = Nothing
End Function
Using cmd : : "cd {dir} & Print \D:LPT1 [file [file]]"
