Создать код ZPL с помощью PHP и распечатать в Zebra Chrome аддон для тестирования?

Хорошо, я скачал аддон Chrome ZPL для тестирования на принтерах Zebra. Но теперь я люблю печатать следующее:

         $qrcode = "012039444";
$name = "Matthew Pitt";
$jobtitle = "CTO funny man";
$company = "Google light company";
$labelcode =<<<AAA
^XA
^FX Left section with QR code.this part doesn't seem to work in simulator
^FO100,100
^BQN,2,10
^FD$qrcode^FS

^FX Right section with name and job title.
^CF0,35,35^FO330,50
^FB300,7,,
^FD$name\&\&$jobtitle^FS
^FO50,500^GB700,1,3^FS

^FX Bottom section only company name
^CF0,35,35^FO30,350
^FB400,2,,
^FD$company^FS
^XZ
AAA;
print_example($labelcode);
//print_example('Hello world');
function print_example($data) {
// You'll need to change these according to your local names and options.
$server = '127.0.0.1:9100';
$printer_name = 'zpl'; // That's effectively the same thing as your GK420d
$options_flag = '-o position=top-left,ppi=203,landscape';
$process_name = 'LC_ALL=en_US.UTF-8 /usr/bin/lp -h %s -d %s %s';
$command = sprintf($process_name, $server, $printer_name, (string)$options_flag);
$pipes = array();
$descriptors = array(
0 => array("pipe", "r"),  // STDIN
1 => array("pipe", "w"),  // STDOUT
2 => array("pipe", "w")   // STDERR
);
$process = proc_open($command, $descriptors, $pipes);
// Couldn't open the pipe -- shouldn't happen
if (!is_resource($process))
trigger_error('Printing failed, proc_open() did not return a valid resource handle', E_USER_FATAL);
// $pipes now looks like this:
// 0 => writeable handle connected to child stdin
// As we've been given data to write directly, let's kinda like do that.
fwrite($pipes[0], $data);
fclose($pipes[0]);
// 1 => readable handle connected to child stdout
$stdout = fgets($pipes[1]);
fclose($pipes[1]);
// 2 => readable handle connected to child stderr
$stderr = fgets($pipes[2]);
fclose($pipes[2]);
// It is important that you close any pipes before calling
// proc_close in order to avoid a deadlock
$return_value = proc_close($process);
// We've asked lp not to be quiet about submitting jobs so we can make
// sure that the print job was submitted.
$request_match = array();
if (!preg_match('/request id is\b(.+)/', $stdout, $request_match)) {
echo ("Print to '$printer_name' failed.  Please check the printer status.");
return false;
}
echo ("Print to '$printer_name' succeeded.  Job $request_match[1].");
return true;
}

[РЕДАКТИРОВАТЬ] это правильная команда для вызова принтера

LC_ALL=en_US.UTF-8 /usr/bin/lp -h zpl -d 127.0.0.1:9100 -o position=top-left,ppi=203,landscape

[РЕДАКТИРОВАТЬ 2] Я пытаюсь с этим php

     $command = 'lp -h 127.0.0.1:9100 -d zpl ' . $labelcode . ' -o position=top-left,ppi=203,landscape';
$pipes = array();
$descriptors = array(
0 => array("pipe", "r"), // STDIN
1 => array("pipe", "w"), // STDOUT
2 => array("pipe", "w")   // STDERR
);
$process = proc_open($command, $descriptors, $pipes);
echo 'test: ' . $process;
