I have a 2820 and here is a link to my current VLAN setup http://red935.co.uk/images/VLAN.jpg

Port 1: Private network 1 connected by a gigabit switch
Port 2: Private network 2 connected by a 10/100 switch
Port 3: Networked printer
Port 4: Public wirless network via a 10/100 switch

What i want to do is have 4 VLAN's to do the following

VLAN0: Private network 1 with network printing
VLAN1: Private network 2 with network printing
VLAN2: Wireless staff access with network printing
VLAN3: Public network

I am however able to see computers on the first 3 VLAN's when i join them with the network printer on port3.

Is there a way around this or am i doing something wrong?
