The intention is the following:

I want to print labels on a label printer. And the aim should be to print a
Label A and a Label B. After each second Label the cutter should cut. I
assumes taht each label is a page. So I called NewPage(). But the printer
will create a new job for each call of NewPage and for each new job the
cutter willl work. So Label A and Label B are not together anymore. (I want
to print 300 labels).
The label printer company told me to send the esacep sequence F which is
0x00c a form feed. And thats what I try to do for hours and hours.
I found out that another way it is possible to send escape sequnces. But
this is workig without Canvas and acomponent which I'm using fpr printing
Barcode needs a Canvas.
So with the first snippet it is possible to send escape sequence but I
cannot use because of the barcode.
The second snippet force no form feed

    OpenPrinter(printername, &PrnHandle, NULL);
    if (PrnHandle != NULL) {
       DOC_INFO_1 DocInfo;
       DocInfo.pDocName = "SessionName";
       DocInfo.pOutputFile = NULL;
       DocInfo.pDatatype = "RAW";

       if (StartDocPrinter(PrnHandle,1,(LPSTR)&DocInfo) <= 0)
          Application->MessageBox("StartDocPrinter", "Error", MB_OK);
       else if (StartPagePrinter(PrnHandle) <= 0)
               Application->MessageBox("StartPagePrinter", "Error", MB_OK);
            else  if (!WritePrinter(PrnHandle,Help,strlen(Help),&size))
                    Application->MessageBox("WritePrinter", "Error", MB_OK);

        if (!EndPagePrinter(PrnHandle))
            Application->MessageBox("EndpagePrinter", "Error", MB_OK);
        else if(!EndDocPrinter(PrnHandle))
            Application->MessageBox("EndDoc", "Error", MB_OK);


        printer->EndDoc();
        ClosePrinter(PrnHandle);
    } else {
        Application->MessageBox("Cannot find printer", "Error", MB_OK);
    }

    char Help[1024];
    sprintf(Help, "\x00c");

    TPrinter* printer = Printer();
    printer->BeginDoc();
    printer->Canvas->TextOut(300, 300, "First page");
    Escape(printer->Canvas->Handle,
           PASSTHROUGH,
           sizeof(Help),
           Help,
           NULL);
    printer->Canvas->TextOut(400, 400, "Next page");
    printer->EndDoc();
