QR Code creation with ESC / POS

[borhane]

hello sir Please help me to change this procedure to language progress Openedge 10.2B thank you in advance.

public void print_qr_code(String qrdata)
{
    int store_len = qrdata.length() + 3;
    byte store_pL = (byte) (store_len % 256);
    byte store_pH = (byte) (store_len / 256);


    // QR Code: Select the model
    //              Hex     1D      28      6B      04      00      31      41      n1(x32)     n2(x00) - size of model
    // set n1 [49 x31, model 1] [50 x32, model 2] [51 x33, micro qr code]
    // epson-biz.com - Epson
    byte[] modelQR = {(byte)0x1d, (byte)0x28, (byte)0x6b, (byte)0x04, (byte)0x00, (byte)0x31, (byte)0x41, (byte)0x32, (byte)0x00};

    // QR Code: Set the size of module
    // Hex      1D      28      6B      03      00      31      43      n
    // n depends on the printer
    // epson-biz.com - Epson
    byte[] sizeQR = {(byte)0x1d, (byte)0x28, (byte)0x6b, (byte)0x03, (byte)0x00, (byte)0x31, (byte)0x43, (byte)0x03};


    //          Hex     1D      28      6B      03      00      31      45      n
    // Set n for error correction [48 x30 -> 7%] [49 x31-> 15%] [50 x32 -> 25%] [51 x33 -> 30%]
    // epson-biz.com - Epson
    byte[] errorQR = {(byte)0x1d, (byte)0x28, (byte)0x6b, (byte)0x03, (byte)0x00, (byte)0x31, (byte)0x45, (byte)0x31};


    // QR Code: Store the data in the symbol storage area
    // Hex      1D      28      6B      pL      pH      31      50      30      d1...dk
    // epson-biz.com - Epson
    //                        1D          28          6B         pL          pH  cn(49->x31) fn(80->x50) m(48->x30) d1…dk
    byte[] storeQR = {(byte)0x1d, (byte)0x28, (byte)0x6b, store_pL, store_pH, (byte)0x31, (byte)0x50, (byte)0x30};


    // QR Code: Print the symbol data in the symbol storage area
    // Hex      1D      28      6B      03      00      31      51      m
    // epson-biz.com - Epson
    byte[] printQR = {(byte)0x1d, (byte)0x28, (byte)0x6b, (byte)0x03, (byte)0x00, (byte)0x31, (byte)0x51, (byte)0x30};

    // flush() runs the print job and clears out the print buffer
    flush();

    // write() simply appends the data to the buffer
    write(modelQR);

    write(sizeQR);
    write(errorQR);
    write(storeQR);
    write(qrdata.getBytes());
    write(printQR);
    flush();
}

In general, please put code inside [ code ] [ /code ] tags.
For sending control codes to the printer, see Progress KB - Using PUT to send Control Codes to a printer

thank you but it didn't work

Ah, sounds like a bot response.

 

[borhane]

simply I want a qr code with an ascii code
like that :

chr(29)  + chr(40) + chr(107) + chr(3) +  chr(00) + chr(49) + chr(65) + chr(50) + chr(00) +
  chr(29) + chr(40) + chr(107) + chr(3) + chr(00) + chr(49) + chr(67) + chr(3) +
  chr(29) + chr(40) + chr(107) + chr(3) +  chr(00) + chr(49) + chr(69) + chr(48) +
  CHR(29) + chr(40) + chr(107) + CHR(3) + CHR(0) + chr(49) + chr(80) + chr(48) + "https://xxxxxxxxxxx.com/" +
  CHR(29) + chr(40) + chr(107) + chr(3) + chr(00) + chr(49) + chr(81) + chr(48) +
  chr(29) + chr(40) + chr(107) + chr(3) + chr(0) + chr(49) + chr(82) + chr(48) +
CHR(27) + CHR(64)+ CHR(47).

Ok, you have figured out how to concatenate strings and use the CHR() function. You still need to figure out how to use CODE tags and how to show a meaningful amount of code.

None the less (I'm on a management conf call so I'm feeling generous):

[ c o d e ] (remove spaces)

output to value( "somefile" ).
put unformatted chr(29) + chr(40) + ... + chr(64) + chr(47).
output close.

[ / c o d e ] (remove spaces)

Is a minimal example that should do what you have asked for.
