    printer_close($handle);

    }

    else "Couldn't connect...";

问题：上面的代码将原始数据发送到打印机并打印正常.. 我有问题

    printer_start_page($handle);
printer_end_page($handle);
printer_end_doc($handle);

不知道如何使用上述命令，

上面的代码打印printer_write（$ handle，“\ t \ t \ t PADIYUR SARVODAYA SANGH”）;这一行然后进入新页面，然后开始打印其他行。

帮我解决这个问题

您需要“开始”文档，然后在需要时创建新页面（不要忘记“结束”它。），然后结束文档。

printer_start_doc($handle, "Document name");

printer_start_page($handle); // Start page 1
// here goes the content of page 1 via printer_write
printer_end_page($handle); // Close page 1

printer_start_page($handle); // Start page 2
// here goes the content of page 2 via printer_write
printer_end_page($handle); // Close page 2

printer_end_doc($handle);

从PHP页面打印RAW，将纸张送入新页面
