如何从php中打印epson tm-t88v中的qr代码

Question

I try print qr code in a epson pos TM-T88V form php and I can't. The information I get from epson-biz.com is no clear at all, and I search and no get any example about the correct steeps to print QR code. I print text no problems, but QR code no work. This is the code I tri follow the epson documentation about ESC-POS:

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');

For example, the documentation I get from epson-biz.com say about Function 165 (I try to follow decimal part in my php code):

    GS ( k   <Function 165>

[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.

Please someone who succeeded in print QR code using comands ESC-POS? I don't know if the order of the Functions (165, 167, 169, 180, 181, 182) are correct.

Answer 1

I see that you have the same problems I had at least below is one example to print QR code, please try to configure your printer on cups linux and after use the commands echo -e "\x" | lpr -P , this example work fine:

1D 28 6B 03 00 31 43 04 1D 28 6B 03 00 31 45 33 1D 28 6B 0d 00 31 50 30 //Note 0d = 13 chars 56 69 76 61 20 43 68 69 6c 65 // 10 chars 1D 28 6B 03 00 31 51 30 00 1B 33 00 00 0A 1D 56 42 00 1B 32 //line spacing, feed, and cut paper...

I hope above code can support you.
