How about embedding the contents of this page in HTML and adding a script to print it out automatically on page load?
如何将这个页面的内容嵌入到 HTML 中并添加一个脚本以在页面加载时自动打印出来？
<?php
$message ="<div>
<table align='center'>
<tr><td><h1>Reporte de Tipo de Documentos</h1></td></tr>
<tr><td><h2>Farmaceutica MDC</h2></td></tr>
</table>
</div>
<div>
<table style='width:960px; margin:0 auto;'>
<tr colspan='7'>
<td><?php echo 'Fecha: '".$time = date('d/m/Y h:i:s A')."; ?></td>
</tr>
<tr bgcolor='#CCCCCC' height='30'>
<td><b>Sr. No.</b></td>
<td><b>Tipo Documento</b></td>
<td><b>Cant. Pasos</b></td>
<td><b>Costo</b></td>
<td><b>Precio</b></td>
<td><b>Balance</b></td>
<td><b>Notifica Cliente</b></td>
</tr>
</table>";
echo "<html><head></head><body>" . $message . "<script type='application/javascript'>window.onload=function(){window.print()}</script></body></html>";
?>
To literally print the HTML code, you can sanitizethe HTML like:
要真正打印 HTML 代码，您可以像这样清理HTML：
echo "<html><head></head><body>" . htmlspecialchars($message, ENT_QUOTES) . "<script type='application/javascript'>window.onload=function(){window.print()}</script></body></html>";
?>

<input type="submit" value="Print" onclick="printIframe(report);"/>
<script>
function printIframe(objFrame) {
objFrame.focus();
objFrame.print();
bjFrame.save();
}
</script>
<iframe name="report" id="report" src="report.php"></iframe>
try calling the form inside an iframe then a link or button that will run the js to print the html/php inside the iframe..
尝试在 iframe 中调用表单，然后调用一个链接或按钮，该链接或按钮将运行 js 以在 iframe 中打印 html/php。
