i need to directly send to the printer a ticket
can someone help me please
This isn't a Phalcon specific question. You will have better luck asking on a more general purpose forum like www.stackoverflow.com.
In my personal experience though, sending a print job to a printer from PHP is pretty much impossible.
You can generate PDF or PostScript file and send it to printer (print-server). Usualy PDF file will generate and download to user on the site.
this is actually pretty easy with message queing instead of using cron/scheduling

<?php
/**
* Receive a print request and print.
*/
$context = new ZMQContext();
$sub = $context->getSocket(ZMQ::SOCKET_SUB);
$sub->setSockOpt(ZMQ::SOCKOPT_SUBSCRIBE, '');
$sub->connect('tcp://server:5566');
while (true) {
$printJob = $sub->recv();
$html = file_get_contents($printJob);
$file = get_temp_dir() . '/printJob_' . sha1($html) . '.html';
file_put_contents($file, $html);

exec('print /d:LPT2: ' . $file);
}whether or not its a good idea is something a lot of people have discussed
