Changing page size on mPDF and getting browser to auto print PDF file on display
提问by methuselah
I am using mPDF (http://mpdf.bpm1.com) to create pdf receipts, but at the moment they only display on a full A4 page.
我正在使用 mPDF ( http://mpdf.bpm1.com) 创建 pdf 收据，但目前它们只显示在完整的 A4 页面上。
I would like to resize them down to a reasonable size because we are using a epson tm-t88iv. This is the first dilemma I have.
我想将它们缩小到合理的大小，因为我们使用的是 epson tm-t88iv。这是我遇到的第一个困境。
The second problem I have involves invoking auto print on the printer attached.
我遇到的第二个问题涉及在连接的打印机上调用自动打印。
I would like to do this when the form is processed (on the same page).
我想在处理表单时执行此操作（在同一页面上）。
But I'm not sure how to implement this into the code I have right now:
但我不确定如何将其实现到我现在拥有的代码中：
<?php
// post
$id = $_GET['id'];
$user = $_GET['user'];
$week = $_GET['week'];
$pRent = $_GET['pRent'];
$rentPaid = $_GET['rentPaid'];
$result = $_GET['result'];
$pDate = date("d/m/Y");
$html = '
<style>

margin-top: 20px;
margin-left: 20px;
}
</style>
<div style="text-align:center; font-family: Arial, Helvetica, sans-serif;">

Try: $mpdf = new mPDF('', 'Letter', 0, '', 12.7, 12.7, 14, 12.7, 8, 8);
试试： $mpdf = new mPDF('', 'Letter', 0, '', 12.7, 12.7, 14, 12.7, 8, 8);
and adjust the values at the end for the margins you want. Check out their documentation
并调整最后的值以获得所需的边距。查看他们的文档
Sorry, not sure about auto printing, but there is some info here
对不起，不知道自动打印，但有一些信息在这里
