I am setting up 4 Vlan.Port 1 is my management port and belongs to Vlan 1 Port 2-12 is Vlan 2. Port 13-24 is Vlan 3. Port 25-36 Vlan 4. There is 3 different companies that uses Vlan 2-4 but i want them to share one printer. The printer is connected to port 48.

Will this work or do i need to have to install a router?

At the moment you have split your switch into 3 virtual switches. In order to move traffic between the switches you will need a router.

Another option would be to get a print server that can have several virtual interfaces on a single physical NIC. For instance, any linux box with a gigabit NIC and CUPS will do.

Note that in any case you will have to ensure that the 3 networks use different IP subnets, otherwise routing would not work.

A print server with 3 virtual interfaces would have different IP addresses one for each network. It will be plugged into say port 37 that will be configured into vlan 2,3,4 tagged.

The Cisco term is "Inter-VLAN Routing". You need a router or a layer 3 switch. –  Mike Christiansen Oct 2 '12 at 6:56
    
@MikeChristiansen thank you, that's interesting. Since ProCurve switches only support 802.1Q VLANs there is not much difference between VLAN and physical network routing. –  Dmitri Chubarov Oct 2 '12 at 12:32
    
There is not much difference between Inter-VLAN routing and physical network routing with Cisco either. With a Cisco router, you just create multiple logical ports (each with their own VLAN) for one physical port. Then, the router will route, as normal, for the directly connected virtual ports. –  Mike Christiansen Oct 2 '12 at 16:18
