<br />
//phpinfo();exit;<br />
//打印机的名字，并初始化<br />
$handle = printer_open("EPSON LQ-735K ESC/P2");<br />
$name = "麻花藤";<br />
$address = "上海市虹梅路1801号";<br />

//转换格式，UTF8打出来乱码<br />
$name = iconv("UTF-8", "GBK", $name);<br />
$address = iconv("UTF-8", "GBK", $address);<br />
<br />
//手动设置纸张的长宽，但这步没启作用，纸张还是按照A4的大小在进行打印<br />
printer_set_option($handle,PRINTER_PAPER_FORMAT,PRINTER_FORMAT_CUSTOM);<br />
printer_set_option($handle,PRINTER_PAPER_WIDTH,320);<br />
printer_set_option($handle,PRINTER_PAPER_LENGTH,250);<br />
<br />
//开启文档<br />
printer_start_doc($handle, "Print"); // Name Document<br />
//打印次数,其实上面printer_set_option也有参数，但也没起作用<br />

	printer_start_page($handle);<br />
	printer_draw_text($handle, $name.$i.$i.$i,150,150);<br />
