HP 3050A A WIRELESS SET UP QUERY?

Hi guys

i recently purchased the above wireless all in one printer and allthough it works ok via usb im having a few problems connecting via wireless

do you need to make adjustments to your router.. or can you simply install the supplied software to the laptop you want to use and then during installation choose wireless and then connect to the printer

this is how i thought wireless printers worked... for example they send out a ssid ( eg HP3050a ) and then you select this and then when prompted insert the security key for the printer

so why do i have to start messing around with my BT home hub (v2.0) .... and ive allready looked in the hub manager and theres nothing i can do..... ( however the latest v3.0 home hub has a wps button which will connect devices by a touch of a button ,however the v2.0 hub does not have this feature )

there is a option on the printer itself called "pin" however when i select this it gives me a code/key and then tells me to configure my router and use that key... configure what ? ...... and as i have allready mentioned there are no options in the hub manager were i can configure a printer anyway ...or am i missing something ?

has anyone had any experience setting up wireless with this particular wifi printer.. and if so any help will be much appreciated

cheers guys !
