Connecting USB scanners and printers to a wireless network

[Peter Goggin]

I don't know if this is the right place to ask these questions. If not 
perhaps some one could point me in the right direction

I have four laptops running ubuntu 14.04.  connected to my wireless 
network. The router has four ethernet ports.
I have four periperals which I wish to make available on the wireless 
network.
1. Samsung CPL-320n - This connects directly to one of the ports on my 
router and can be used by all four laptops.
2. Brother HL2130 laser printer. This only has a usb port.
3 Epsom XP-100 printer/scanner. Only has usb port
4 Epson 3490 photo scanner. This only has a usb port.

I need the printer function of the xp100 and the HL2130 available on the 
wireless network.
  I have been give two netgear PS121-V2 print servers.

I have no information on them. Googling gives me the distinct impression 
that they are windows devices. I have connected one to an ethernet port 
but the laptops do not see it. Do I need drivers for these devices? Can 
they be used with linux machines?

Thanks for any advice or help.
