Just leave out the HEX keyword...

char myString[12] = {0x54, 0x65, 0x73, 0x74,0x4D, 0x63, 0x4B, 0x65, 0x6C, 0x6C, 0x61, 0x72};

void setup() 
{
  Serial.begin (9600);
  delay(200);
  Serial.println();
  
  for (uint8_t x = 0; x < 12; x++)
  {
    Serial.print(myString[x], HEX); 
    Serial.print(" ");
  }

  Serial.println();

  for (uint8_t x = 0; x < 12; x++)
  {
    Serial.print(myString[x]); 
  }
}

void loop() 
{

}

Output

54 65 73 74 4D 63 4B 65 6C 6C 61 72
