php - How to Connect to Zebra Printer ZD220 or Gc420t and print?

Solution:

We use fputs($fp, $out) instead of fwrite($fp, $out), with $out being some EZPL/ZPL code in a string.

$fp = fsockopen($printer['ip'], $printer['port'], $errno, $errstr, 10);
if (!$fp) {
    // code if no connection found
} else {
    $out = "some EZPL code as string";
    fputs($fp, $out);
    fclose($fp);
}
