Delayed printout

Hey all,

short info about before and after settings and my problem:

Before:

- Avaya Switches (with layer 3)

- Other Firewall (just for outgoing traffic)

Now:

- Avaya Switches (layer 3 removed)

- FortiSwitch / FortiGate (OS: 6.0.3)

Problem:

Before we switched to FortiGate and FortiSwitch as Layer 3 we could just print from pc net to printer net and it works as expected.

Now we got the problem, that many (not every printjob) are delayed. We press print on Windows and after 1-3 Minutes the printjob starts.

Thats pretty annoying, because some people are printing every few minutes.

We got no rule intern/intern (vlans) rule that block ports.

So does someone know or got the same problem and has some hints?

thx
