|But I wish to access the printers, scanners etc thru a wireless access point. Unfortunately both work seperately but not simultaneously.|
Explain that statement please.
I don't understand "separately but not simultaneously".
Most places have a wireless network that is separate from their internal network for security reasons. It's a lot harder to break into a wired network with nefarious intent than it is to break into a wireless.
In fact, our security guy cracked WEP encryption in under 30 minutes and assures me he can crack WPA encryption as well only it would take longer.
Where I work, we have a separate wireless network that provides only internet access for the above reason. If a staff member from another location arrives with their laptop, they connect to this and use their VPN to access internal resources.
I would not recommend setting your wireless up to allow access to your internal network, that's just asking to get hacked.
