Connect B110a to laptop without a router

[JJxx]

Just bought this printer and didn't realise that I needed a router.  It seems that it is possible to connect without one but I need simple step by step instructions!!!  I have a Dell laptop running Windows 7.  Help please

Thanks.  I set up the connection but got the error

Did you insert the installation CD that came with the product and install the software?

Connect to the ad hoc network profile you created on your laptop.

[JJxx]

Yes. Still the same error.

Change the Secuity type to WEP from WPA2.

I beieve Ad hoc only supports WEP security.
