Display long text

[a-phe-lei-a]

Hello,
I use you library but I don't have the possibility to show a long text. If my text is up to 40 charter this is cutting on two part and the 41 charter and after is showing on the second line.

This is my code :

#include <LiquidCrystal_I2C.h>
#include <Keypad_I2C.h>


const byte keypadRow = 4;
const byte keypadCol = 4;

byte rowPins[keypadRow] = {0,1,2,3}; // Row 0,1,2,3
byte colPins[keypadCol] = {4,5,6,7}; // Col 0,1,2,3

int keypadArdesse = 0x22; // A0 and A2 GND and A1 5V

char keys[keypadRow][keypadCol] = {
  {'1','2','3','A'},
  {'4','5','6','B'},
  {'7','8','9','C'},
  {'*','0','#','D'}
};

const byte lcdRow = 2;
const byte lcdCols = 16;

int lcdAdresse = 0x27;    // Default adress

Keypad_I2C keypad = Keypad_I2C(makeKeymap(keys), rowPins, colPins, keypadRow, keypadCol, keypadArdesse);
LiquidCrystal_I2C lcd = LiquidCrystal_I2C(lcdAdresse,lcdCols,lcdRow);

bool backlight = true;

char txtFirstLine[] = "An den exis ti na kanis ela na pame mia megali volta opou 8elis ";

void setup(){
  Serial.begin(9600);
  keypad.begin();
  lcd.init();
  lcd.backlight();
  lcd.setCursor(0,0);
  lcd.printstr(txtFirstLine);
}

void loop(){
  char key = keypad.getKey();
  if(key){
    Serial.println(key);
    if(key == 'A')
      lcd.scrollDisplayLeft();
    if(key == 'B')
      lcd.scrollDisplayRight();
  }
}
