can anyone tell me how to print CDs on a Pixma iP4000?

[WilfSell]

Got a Pixma iP4000 an want to print directly onto the CD. We have some sort of cassette that came with the printer but no idea how it works. Tried to download the manual from Canon (lost ours obv) but the cheeky rip off merchants are charging!

Any expert help out there?

I have a Pixma IP4000. I'll look for the handbook if you can wait until lunchtime.

Have never printed on CD before personally.
