printer扩展的一些使用疑问

//phpinfo();exit;

//打印机的名字，并初始化

$handle = printer_open("EPSON LQ-735K ESC/P2");

$name = "麻花藤";

$address = "上海市虹梅路1801号";

//转换格式，UTF8打出来乱码

$name = iconv("UTF-8", "GBK", $name);

$address = iconv("UTF-8", "GBK", $address);

//手动设置纸张的长宽，但这步没启作用，纸张还是按照A4的大小在进行打印

printer_set_option($handle,PRINTER_PAPER_FORMAT,PRINTER_FORMAT_CUSTOM);

printer_set_option($handle,PRINTER_PAPER_WIDTH,320);

printer_set_option($handle,PRINTER_PAPER_LENGTH,250);

//开启文档

printer_start_doc($handle, "Print"); // Name Document

//打印次数,其实上面printer_set_option也有参数，但也没起作用

for($i=1;$i<=2;$i++)

{

printer_start_page($handle);

printer_draw_text($handle, $name.$i.$i.$i,150,150);

printer_draw_text($handle, $address.$i.$i.$i,250,250);

printer_end_page($handle);  //

//打印图片

//printer_start_page($handle); // Start Logo

//printer_draw_bmp($handle, "c:logo.bmp", 60, 0);  // Logo Dir, lenght H , With V

//printer_end_page($handle);  // End Logo

}

printer_end_doc($handle);   // Close document 

printer_close($handle);     // Close Pritner
