TCPDF打印从入门到精通

1. TCPDF的模块导入

TCPDF的官网为https://tcpdf.org

官方文档有几十个例子；详情参看官方文档！

2. 使用 TCPDF打印

例如：横版表格打印并自动分页

/**
     * 打印
     */
    public function actionPrint($id)
    {
        //设置无布局
        $this->layout = false;

        //获取打印数据
        $model = $this->findModel($id);

        if(!($model->is_del == 0)){
            throw new ForbiddenHttpException("该单据无法打印");
        }

        $wmsCheckDetail = new \backend\models\WmsCheckDetailSearch();
        $dataProvider = $wmsCheckDetail->searchByCheckId($id);

        //生成页面内容
        $content = $this->render('print', [
            'model' => $model,
            'dataProvider'=>$dataProvider,
        ]);
        //打印对象
//        $pdf = new \TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT,true, 'UTF-8', false);
        $pdf = (new \TCPDF('L', 'mm', array(240, 140), true, 'UTF-8', false));
        //设置无打印头
        $pdf->setPrintHeader(false);
        $pdf->setPrintFooter(false);
        //设置PDF打印纸张的编剧
        $pdf->SetMargins(20, 20,20);
        //设置单元格内边距
        $pdf->setCellPaddings(0, 0, 0, 0);
        //设置自动进入下一页
        $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_RIGHT);
        $pdf->AddPage();
        //设置字体
        $pdf->SetFont('stsongstdlight', '', 10);
        $pdf->writeHTML($content, true, false, true, false, '');
        $pdf->lastPage();
        $pdf->get('库存盘点.pdf');

    }

<style type="text/css">

$content 返回的是html页面打印的具体内容

纸张竖着打印用

$pdf = new \TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT,true, 'UTF-8', false);

纸张横着打印使用

$pdf = (new \TCPDF('L', 'mm', array(240, 140), true, 'UTF-8', false));

即宽度为240，高度为140的A4纸

注意：

重要的是纸张的自动分页，如遇到表格也会形成两个表格

$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_RIGHT);
