No pasa nada después de ejecutar la función. Es como si el código no tocara a la impresora en absoluto.

ACTUALIZAR Método 1 es lo más cercano que puedo llegar a imprimir el archivo. Después de ejecutar el comando, hay un ícono de la impresora en la barra de estado que indica que la impresora ha recibido una llamada y ha recibido datos de mi código, pero aún así, no imprime nada. Ayuda...

Answer 1

si está mapeado en un puerto paralelo o com, puede abrirlo directamente:

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

Answer 2

De acuerdo, así es como logré hacer que esto funcione. No es la mejor opción, pero quería ... funciona.

1) Uso la misma función, pero escrito en C ++, tomado de aquí 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;
}

Obtuve el archivo RAWPRN.EXE desde allí, puse mi código EPL en un archivo txt. Finalmente, usa Shell para ejecutarlo

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

Answer 3

Lo que me gusta hacer es hacer algo similar a su Método 2, pero guardarlo en un archivo (los datos de la impresora bruta) y luego hacer una copia de archivo en la ruta UNC.

copia de archivo "C: / label.txt" / computername / sharename

Funciona para mi.

Answer 4

Mi solución para Zebra

1. Crear una impresora genérica / de texto en Windows y luego enviarla al archivo sin formato a esta impresora
2. En las configuraciones avanzadas de impresoras Zebra -> otras, hay un carácter de paso a paso. Puede enviar texto sin procesar con esto a esta impresora.
