在PHP中使用mpdf，在新选项卡中打开打印对话框 [英] Using mpdf in PHP, open print dialog box in a new tab

问题描述

我正在使用mPDF库在PHP中创建报告。直到现在输出被保存为pdf文件，我需要通过打开自动下载的文件手动打印出来。



我需要的是我点击后立即我的PHP网页上的打印按钮，mPDF应创建输出并立即使用默认打印机打印文档。我甚至不需要任何中间对话框，可以再次获得打印确认。简单地说，点击基于PHP的网页按钮应该将打印命令发送到默认打印机。



以下是我的代码：

 include（  \ mpdf\mpdf.php ）; 
 $ mpdf = new mPDF（' '，'  A4'）; 
 $ mpdf-> WriteHTML（$ a）; 
 $ mpdf->输出（'  r.pdf'，'  D'）; 

我还能做些什么来实现我的需求？



我尝试过的事情：



我尝试过以下代码：

 include（   \ mpdf\mpdf.php）; 
 $ mpdf = new mPDF（' '，'  A4'）; 
 $ mpdf-> WriteHTML（$ a）; 
 $ mpdf-> SetJS（'  this.print（）;'）; 
 $ mpdf->输出（）; 

此解决方案出现两个问题：



1.它仍会打开一个打印确认对话框。

2.它打开当前标签中的打印预览和对话框，这意味着点击打印在单击打印之前，我无法获得与之相同的界面。为此，我必须单击浏览器上的后退按钮，这不是一个好的解决方案。

解决方案

mpdf = new mPDF（' '，' A4' ）;

mpdf->的WriteHTML（

一个）;

I am creating a report in PHP using mPDF Library. Till now the output is saved as a pdf file which I need to print out manually by opening the auto downloaded file.

What I need is as soon as I click on Print button on my PHP Web page, mPDF should create the output and immediately print the document using default printer. I even donot need any intermediate dialog box that would again get a confirmation to print. Simply, clicking on PHP based web page button should send the print command to the default printer.

Below is my code:

include("\mpdf\mpdf.php");
$mpdf=new mPDF('','A4');
$mpdf->WriteHTML($a);
$mpdf->Output('r.pdf', 'D');

What else I can do to achieve what I need?

What I have tried:

I have tried the following code:

include("\mpdf\mpdf.php");
$mpdf=new mPDF('','A4');
$mpdf->WriteHTML($a);
$mpdf->SetJS('this.print();');
$mpdf->Output();

This solution comes up with two problems:

1. It still opens a dialog for print confirmation.
2. It opens the print preview and the dialog box in my current tab which means that on clicking print, I cannot get the same interface on which I was working before clicking Print. For that, I have to click on back button on the browser which is not a good solution.

解决方案

mpdf=new mPDF('','A4');

mpdf->WriteHTML(

a);
