Canon Pixma IX4000 Printing Problems in CS3 InDesign

Hi

I bought this printer when I was on Tiger system software. I have upgraded to Leopard 10.5.6 and when I go to my print pane in InDesign CS3 and go to paper size in set up, I can only get "defined by driver". I have lost all my paper sizes which I could select when I was on Tiger. I can only print out A4 pages and not landscape, just portrait.

Please help

Have you tried downloading the latest driver from Canon's website?

Thanks for your response, I have downloaded version 4.83 from their website. I am printing to a shared printer. The Mac (G4) it is connected to to is on Tiger not Leopard. Could that be a problem? My Mac is Macbook Pro.
