Char Array Client.Print Arduino - c++

Question

I am trying to read a QR code and send it the phpMyAdmin. I am using a DE2120 1D2D scanner and a UNO. The problem is with the printing , on the serial monitor looks like a string but in the php the each character from the code is printed on a new line, the idea is to client.print the entire code on the same row.
Code bellow:
#include "SparkFun_DE2120_Arduino_Library.h"
#include "SoftwareSerial.h"
#include <Ethernet.h>
#define BUFFER_LEN 40
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xEE }; //
IPAddress ip(192, 168, 1, 22 ); //
IPAddress gateway(10, 74, 0, 1);
IPAddress subnetMask(255, 255, 255, 192);
EthernetClient cliente;
char server[] = "192.168.1.15"; //
SoftwareSerial softSerial(3,2);
DE2120 scanner;
char scanBuffer[BUFFER_LEN];
String QR;
void setup() {
Serial.begin(115200);
softSerial.begin(9600);
Serial.println(scanner.begin(softSerial));
Ethernet.begin(mac, ip);
IPAddress newSubnet(255, 255, 255, 192);
Ethernet.setSubnetMask(newSubnet);
Serial.print("Ethernet.localIP: ");
Serial.println(Ethernet.localIP());
Serial.print("Ethernet.gatewayIP:");
Serial.println(Ethernet.gatewayIP());
Serial.print("Ethernet.subnetMask:");
Serial.println(Ethernet.subnetMask());
if (cliente.connect(server, 8080)) {
Serial.println("Connected to the server");}
}
void loop() {
delay(200);
if(scanner.readBarcode(scanBuffer, BUFFER_LEN)){
Serial.println("QR availbale ");
for(int i = 0; i < strlen(scanBuffer); i++){ // Production Order
Serial.print(scanBuffer[i]);
QR = String(scanBuffer[i]);
(cliente.connect(server, 8080));
cliente.print("GET /ethernet/data_qr.php?");
cliente.print("QR=");
cliente.println(QR); // I tried also with client.print(QR) followed by client.println(), no chance.
//client.println();
cliente.stop();
}
Serial.println();
}
}
Serial monitor - QR is a String
Client.print result
I tried:
To convert the Char scanBuffer[i] to String and than printed. - 0 results
To store the serial monitor value ov scanBuffer[i] in a variable and the printed. - 0 results
Client.println / Client.print
What can I try , some ideas on order to client.print the QR content in the same row.
Thank you ! :D
