我们都知道，按CTRL+p可以将网页保存为pdf，然后保存为pdf。但是如何直接使用php来完成呢？请注意，该网页是预先设计的，我需要将其保存为pdf
您可以使用TCPDF，看看这个给出这个结果的例子；

一个更具体和简化的示例，包括从文件中检索HTML。
未经测试，但用作概念；
<?php
// Include the main TCPDF library (search for installation path).
require_once('tcpdf_include.php');
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set font
$pdf->SetFont('dejavusans', '', 10);
// add a page
$pdf->AddPage();
// create some HTML content
$html = file_get_contents('path/to/file/with.html');
// output the HTML content
$pdf->writeHTML($html, true, false, true, false, '');
// reset pointer to the last page
$pdf->lastPage();
//Close and output PDF document
$pdf->Output('example_006.pdf', 'I');
我终于找到了解决方案，下面是项目标准：
- Windows操作系统
- 文档必须首先以HTML呈现
- HTML必须另存为。PDF
- PDF必须发送到打印机
为了实现相同的解决方案，您需要安装Google Chrome，并且路径(通常为C:''Program Files(x86(''Google''Chrome''Application(应该在您的环境变量中，否则在调用Chrome.exe:时需要完整的路径
//HTML content
$html = 'Your html here'; //Make sure to include references to any style sheets
//Name of HTML file
$htmlFileName = 'test.html';
//Name of PDF file
$pdfFileName = 'test.pdf';
//Command that will be executed using exec()
$savePDFCMD = "chrome --headless --disable-gpu --print-to-pdf=".$_SERVER['DOCUMENT_ROOT']."/<PROJECT_DIRECTORY>/$pdfFileName ".$_SERVER['DOCUMENT_ROOT']."/<PROJECT_DIRECTORY>/$htmlFileName";
//Kill command for Chrome process
$endChromeCMD = 'taskkill /IM chrome.exe';
//Create HTML file at project root
file_put_contents($htmlFileName, $html);
//Convert HTML to PDF using Headless Google Chrome (there will be header and footer info such as timestamps and file location - This can be removed with CSS).
exec($savePDFCMD);
//Ends chrome.exe process
exec($endChromeCMD);
//You will need to know the printer's IP address and the port it receives files on (ask your IT manager)
$fp = pfsocketopen("<PRINTER_IP_ADDRESS>", Port);
//Sends PDF to the print que
fputs($fp, file_get_contents($pdfFileName));
//Close connection after file has been printed
fclose($fp);
//Deletes temp files used for printing
unlink($htmlFileName);
unlink($pdfFileName);
