推荐答案

问题解决:

之前:

[...]
$pdf = new TCPDF("L", "mm", array(80,30) , true, 'UTF-8', false);
[...]
$pdf->AddPage();
[/code]

之后:

[code]
[...]
$pdf = new TCPDF("P", "mm", array(80,30) , true, 'UTF-8', false);
[...]
$pdf->AddPage('L', '', false, false);
[/code]

问题是构造函数的页面方向给系统造成了混乱:默认竖屏就可以了，我只要把添加页面方向改成横屏就解决了.

The problem is the constructor page orientation that create confusion to the system: default portrait is ok, I have only to change the Add page orientation to Landscape and the problem is solved.

再次感谢您的关注.
