我有一个名为“Start STP 100”的打印机收据,我的网站使用mPDF库创建一个带收据格式的PDF .
以下代码是我生成PDF的类:
class printdoc
{
private $width;
public function __construct()
{
require('mPDF/mpdf.php');
$this->width = 80;
// Default values
$this->mPDF = new mPDF('utf-8', array($this->width, 1000), 9, 'Segoe UI', 5, 5, 0, 0, 5, 5, 'P');
$this->mPDF->setAutoTopMargin = 'pad';
}
public function write($html, $url)
{
$this->mPDF->WriteHTML($html[0]);
$this->mPDF->page = 0;
$this->mPDF->state = 0;
unset($this->mPDF->pages[0]);
$p = 'P';
// At this point the Y size is set according to the dimensions of the PDF
// So the value '1000' set in the __construct() has no effect.
$this->mPDF->_setPageSize(array($this->width, $this->mPDF->y), $p);
foreach($html as $content)
{
$this->mPDF->addPage();
$this->mPDF->WriteHTML($content);
}
$this->mPDF->Output($url);
}
public function create($data)
{
$html = '<html>';
$html .= ' <head></head>';
$html .= ' <body>';
$html .= $this->header($data);
$html .= $this->body($data);
$html .= $this->footer($data);
$html .= ' </body>';
$html .= '</html>';
return $html;
}
}
现在为了创建收据并保存它,我有这个功能:
function printreceipt($data)
{
require('printdoc.php');
$file = 'test-receipt.pdf';
$html = $this->printdoc->create($data);
$this->printdoc->write($html, $file);
}
使用Chrome PDF Viewer时生成的文件具有正确的尺寸(宽度和高度),但是当发送到打印机时,它会打印太多纸张 .
基本上这是PDF的大小(在浏览器上查看时):

这是打印时纸张的大小:
---
| |
| |
| |
| |
| |

是否有任何方法强制mPDF切割文件或在我的 html
之后写任何命令以便打印机解释和剪切?

似乎Start STP 100有一个谷歌Chrome的错误,创建了额外的纸张 . 用firefox解决了这个问题 .
