Our network data should not be accessible. I was thinking along the same line of only allowing access to the printers IP.
It sounds like it can be done with Cisco but does anyone know if it can be done with procurve?

Browse All TopicsI have a printer/copier that is attached to the network, and ProCurve Switch 4204vl in my network.
We are going to rent some space out but they want to use our shared printer for large print jobs.
We don't want to run another network cable so I was thinking we can do something with the VLAN capabilities of the switches. I am unsure since I know the concept of VLANs but never had the chance to apply them.
Is it possible to share a network printer with another group of computers without adding them to the domain?
If so, what are the general step?

Here's the issues I see. Printers, as far as I've seen, don't allow for multiple IP Addresses - if they did, then this wouldn't be an issue. Since they don't you would have to have BOTH networks use the SAME IP range. Then you could just add the printer as a "local" printer to their server (designated server PC) and they could print through it that way. While this COULD work fine, the problem is they would be on the same logical LAN as your network. Now if you have things properly secured, it shouldn't GENERALLY be a big problem... BUT, anytime you allow access to the same physical network you are creating a security hole. The one thing I can think of that would allow this to work AND keep you both on separate LANs is to buy a second print server - or even another computer.
The config would look like this:
built-in network goes to your physical network
a USB OR parallel print server would then be connected to the device's appropriate port (assuming it has one) and then that print server would be connected to the other physical network. Hardware cost $50-100.
OR
buy a separate (cheap, small) PC (or recycle an older one), set that up the print server. Put two network cards and DO NOT enable routing on it. One network card goes to your network, the other goes to their network - each with appropriate IPs (each network will need to use a different logical subnet for this work). Not quite as secure as the first idea, but if the device doesn't have a USB or Parallel port for a second connection of a print server, then this is probably the best you'll get. Hardware Cost $200-400.
Of course, printers and scanners are DIRT CHEAP. You could just say "sorry, no" and they can buy a multi-function laser or inkjet scanner/copier for $100-$400 or more, depending on their needs...
Are you sharing an internet connection too?
If you are, you could setup another subnet (network or vlan) and use your gateway router like a router on a stick. IE: set one route up as destination IP=shared printer IP, route=original subnet. This way packets for other printer are passed through to the the printer's subnet and other packets destined for IP's within that subnet are directed toward the internet (through the default route) and are dropped.
If the have their own internet service, you could get a cheap little router and install between the 2 subnets (statically set LAN port to new subnet and WAN port to domain subnet), then set a route in their gateway router for destination=the printer's IP and point it to the IP on the LAN port of your new little router. Make sure that the new router has NAT turned on and DHCP turned off.

You can share the printer between the two networks. If you give the other network access to your current subnet network then can access the printer by IP address. If you allow connection through IP address you by pass the need for authentication from your domain which will allow for easier setup.
The steps would be to create another VLan for the other set of computers give the Vlan access to your current network then setup the printer as you would on your network.
The one problem is that you give the other set of computers access to your network. In Cisco switches you can setup Vlans to only allow access to certain IPs or ports but I'm not sure with the Procurve.
