title: "No Response" With PHP and Canon devices
body: <p>I'm developing a little monitoring PHP interface. I'm using a lot SNMP for Windows Server and Synologys and it's working well. But with Canon printers, I have always "No response from [IP]". It's working with all brands but not with Canon.</p>
  
  <p>Here's the code I'm using:</p>
  
  <pre><code>$snmp = new \Snmp(1, "192.168.2.173", "public",1000000,2); 
  $toners['black'] = $snmp-&gt;get('.1.3.6.1.2.1.43.11.1.1.9.1.1'); 
  var_dump($snmp-&gt;getError()); 
  var_dump($toners);
  </code></pre>
  
  <p>Can someone help me please?</p>
