[三周以来（我想我真的很慢！），我尝试使用TCPDF自己的示例以及在此站点上找到的一些建议，以弄清楚如何使用数据库记录来执行此操作。当其他人询问如何使用第三方补丁（类）来使事情顺利进行时，Asuni先生已经回应了一些帮助请求，仅是可以在没有此类的TCPDF中完成。无论出于什么原因（也许是我自己的误解），我都无法使用TCPDF通过他的列方法打印标签。
我也不愿意放弃TCPDF来支持其他可能的解决方案（我不会讨论的原因）。 PHP TCPDF Export for Standard Address Labels是在通过切换到fpdf17获得所需功能时此处提出/解决的问题的示例。
所以我一直坚持到今天，甚至尝试了一些用法语编写的精彩代码，但我无法说服它来创建所需的结构。
因为像我上面提到的那样的问题已经（在本网站和其他地方）被“击中”了很多次，而看起来似乎没有解决方案，所以我决定尽我所能阅读工作代码，直到我感到疲倦为止，然后进行测试，重新测试并测试更多。
我终于找到了一种从数据库制作PDF的方法，该方法可以使PDF包含6页标签（2张，三页向下）的页面，格式为AVERY 5164。而且我无需使用TCPDF的列方法或任何第三方修补程序或类就可以做到这一点。
几乎每个人只要密切注意我代码中变量的含义，就应该能够根据自己的需要更改我的解决方案。
我很肯定，必须有一种更优雅（正确的方法）来获得我得到的结果，所以我非常乐意接受有关如何改进我的代码的建议。
而且，在被烧伤之前，是的，我知道数据库调用必须是PDO。我对客户可以访问的内容感到困惑。
最后，只是想知道制作记录数量不同的各种PDF需要多长时间：12条记录（2页）-> 4秒下载激活200条记录-> 44秒文件大小是合理的（不过，我没有写下任何内容。...对不起！）

我希望我不会通过稍微更改代码来删除敏感信息来破坏任何东西。感谢您提供的网站-我学到了很多东西，希望现在能帮助到别人！
[看看我的解决方案-它可以打印24个标签-3 * 8到A4中。只需对宽度，高度和$ qty进行简单的更改，就可以得到2 * 6。

仅在2天前看到此问题。我认为这只是一个宽度和高度计算问题。
以下解决方案可能对几乎一维TCPDF标签打印有用。该示例适合4列，并支持分页符，然后调整所需的参数。

'text' => true,
'font' => 'helvetica',
'fontsize' => 8,
'stretchtext' => 4
);
// Set some content to print

$label_h_margin = $label_h - 6.5; // Label height margin - Do not change except you know what you are doing
// print a block of text using Write()

$pdf->SetFont('helvetica', '', 10); // cid0jp or msungstdlight can display chinese

$x = $pdf->GetX();
$y = $pdf->GetY();
for ($i=1; $i <= 80; $i++) {
