HP LJ4600 Printer issues.

Ok, so I have a LaserJet HP 4600dn on my LAN. It is a stand-alone printer under no server. I have issued it a static DHCP to make it easier to managem, but I have been having an issue with it.

Well, I'm able to install it on my nodes, but the problem is that sometimes they can print and sometimes they are unable. It just fails to print. And if they bug it enough, it will go through successfully like nothing was wrong!

What's going on with my setup? Did I do something wrong??? Any help I would gladly appreciate!

Thanks!
