    Hello,
    I am working on a project which is generates invoice using php & html. i want to print that invoice directly to default printer using php. Seems printer_write function prints only source code & not the output view. So i created invoice into PDF using FPDF. Still i cant able to print PDF file using printer_write function. Any suggestions?

    My sample code:
    $pHandle = fopen("files/sample.pdf", "r");
    $handle = printer_open("HP LaserJet 1020");
    printer_set_option($handle, PRINTER_MODE, "RAW");
    printer_write($handle,$pHandle);
    printer_close($handle);

    Why using PHP for this. Use this in HTML: <body onload="window.print();">

    Second option is this.
    at the very end of your HTML page, put this code:

    <script type="text/javascript">
    window.print();
    </script>

    This is recommended by some,
    argument being that the printing starts only after the page is completely loaded...

    However, the onload attribute inside <body> gets executed only when the page is completely loaded...
    So pretty much same thing.
