How print qr code in epson tm-t88v from php(如何从php打印EPSON TM-T88V中的二维码)

本文介绍了如何从php打印EPSON TM-T88V中的二维码的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我尝试在Epson pos TM-T88V表单php中打印二维码,但无法打印。我从Epson-biz.com获得的信息根本不清楚,我搜索也没有得到任何关于打印二维码的正确步骤的示例。我打印文字没问题,但二维码不行。这是三个遵循Epson文档关于ESC-POS的代码:

if(($handle = @fopen("LPT1", "w")) === FALSE){
    die('I can't print, check your connection');
}

fwrite($handle,chr(27). chr(64));//restart    
fwrite($handle, chr(27). chr(100). chr(0));
fwrite($handle, chr(27). chr(33). chr(8));
fwrite($handle, chr(27). chr(97). chr(1));
fwrite($handle,"=================================");
fwrite($handle, chr(27). chr(100). chr(1));
fwrite($handle, chr(27). chr(32). chr(3));
fwrite($handle," No 1005 ");
fwrite($handle, chr(27). chr(32). chr(0));
fwrite($handle, chr(27). chr(100). chr(0));
fwrite($handle, chr(27). chr(33). chr(8));
fwrite($handle, chr(27). chr(100). chr(0));
fwrite($handle, chr(27). chr(100). chr(1));
fwrite($handle,"=================================");
fwrite($handle, chr(27). chr(100). chr(3));
// to here work, but the rest is the problem:
    fwrite($handle, chr(29).chr(40).chr(107).chr(4).chr(0).chr(49).chr(65).chr(50).chr(0));  // Function 165
    fwrite($handle, chr(29).chr(40).chr(107).chr(3).chr(0).chr(49).chr(67).chr(20)); // Function 167 
    fwrite($handle, chr(29).chr(40).chr(107).chr(3).chr(0).chr(49).chr(69).chr(48)); // Function 169
    fwrite($handle, chr(29).chr(40).chr(107).chr(3).chr(0).chr(49).chr(80).chr(48)); // Function 180
    fwrite($handle,"TEXTO DE PRUEBA DE CODIGO QR");  // this text go to QR
    fwrite($handle, chr(29).chr(40).chr(107).chr(3).chr(0).chr(49).chr(81).chr(48)); //Function 181
    fwrite($handle, chr(29).chr(40).chr(107).chr(3).chr(0).chr(49).chr(82).chr(48)); //Function 182

fwrite($handle, chr(27). chr(100). chr(6));
fwrite($handle, chr(29). chr(86). chr(1));// cut paper


fclose($handle); 
$exitmsj = shell_exec('lpr LPT1');

例如,我从epson-biz.com获得的文档中提到了函数165(我尝试在php代码中跟随小数部分):

    GS ( k   <Function 165>
________________________________________
[Models]    •   TM-J2000
•   TM-J2100
•   TM-L90
•   TM-P60
•   TM-P60II
•   TM-P80
•   TM-T20
•   TM-T20II
•   TM-T70

•   TM-U230
[Name]  QR Code: Select the model
[Format]    ASCII       GS      (       k       pL      pH      cn      fn      n1      n2

[Range] (pL + pH × 256) = 4 
cn = 49 
fn = 65 
n2 = 0 
n1: different depending on the printers
[Default]   n1 = 50, n2 = 0
[Description]   Selects the model for QR Code.
n1  Function
49  Selects model 1
50  Selects model 2
51  Selects Micro QR Code

[Notes]    Settings of this function affect the processing of Function 181 and 182.
   Settings of this function are effective until ESC @ is executed, the printer is reset, or the power is turned off.

有没有人用Comands ESC-POS成功打印出二维码?我不知道函数(165、167、169、180、181、182)的顺序是否正确。

推荐答案

更改:

fwrite($handle, chr(29).chr(40).chr(107).chr(3).chr(0).chr(49).chr(80).chr(48)); // Function 180

为此:

fwrite($handle, chr(29).chr(40).chr(107).chr(31).chr(0).chr(49).chr(80).chr(48)); // Function 180

<Function 180> GS ( k pL pH cn fn m d1…dk (cn = 49, fn = 80)

k = (pL + pH x 256) – 3

k=要打印多少字符?发送"tex to de Prueba de CODIGO QR"(28)。

k = (31 + 0 x 256) - 3
k = (31 + 0) - 3
k = 31 - 3
k = 28

所有其他设置只遵循命令的默认值。
