Reading data arrays "expected unqualified-id before 'sizeof'" where an I wrong

This is a follow on from an other question but a different problem

I can’t see where Im going wrong here …I have tried all sorts but Im just getting no where

//This is the data I need to send to a machine to get it to print a test code
byte seq = {12, 33, 21, 11, 21, 66 , 43, 21, 21, 24, 17, 33,};

void setup() {
Serial.begin(9600);
}

void loop() {

//This will write to an RS232 level converteter then to a barcode printer
Serial.write(seq.sizeof(seq));

//This is just a indicator to show the data is being read and will be deleted when finished
Serial.print(seq.sizeof(seq));

//leave a gap between each interation
Serial.print(" ");
delay(200);
}

Domino_test2.ino (518 Bytes)

Serial.print(seq.sizeof(seq));

should be

Serial.print(seq, sizeof(seq));

So simple ......if you know it !!!

Thank you so much
