I'm having trouble with an HP LJ 1022n printer. The connection is as follows:

  1. Printer connected via usb to desktop (shared options set, discoverability, etc)
  2. Desktop connected to switch and set up to a windows 2008 r2 server. (*other computers connect to the switch and server as well through LAN.)
  3. Wifi Router connected to switch
  4. My laptop connected to network via wifi.
  5. Other desktop also connected to Wifi Router via LAN

We used to be able to print to the HP, but for some reason now all the laptops that connect via wifi can't and the desktop connected to the Wifi Router via lan can't either. The thing is that the computers connected to the switch can.

The printer is online for those computers, but for us it says server offline. Any clues?

Is the wireless router connected to the switch via it's WAN interface? If so, that's the problem. –  joeqwerty Mar 1 '13 at 16:03
    
Thanks Joe, But no, the wan port is used by a ADSL modem to provide internet access. –  Daniel_M Mar 1 '13 at 16:27
    
How do the wireless router connected devices get their ip configuration? Via DHCP? If so, do they get it from the wireless router? Are they getting ip addresses in the same subnet as the switch connected devices? –  joeqwerty Mar 1 '13 at 16:32
    
At least my laptop's ip is given via DHCP through the wireless router. The IP is in the same subnet as the desktop with the printer. –  Daniel_M Mar 1 '13 at 16:40
    
Can you access the switch connected desktop or any other switch connected host via ping, UNC path, etc. from a wireless router connected host? –  joeqwerty Mar 1 '13 at 16:43
