Installed printer, can't find it on computer

[ziggy1]

I decided to get a USB cable for the Canon MP650 I bought yesterday. I connected it, aligned the head and printed out a test page and it looks ok.

I used the disk that came with the printer and it said everything was installed successfully. Do I need a driver? That should be on the disk, right?

I'm using an iMac OS X v 10.5.8

I wanted to print a test photo, so I clicked on One-Click Photo Print and received an error message: The operation cannot be continued because a printer supporting Photo Print is not installed.

I clicked on System Preferences-Print & Fax, and there's nothing there. I clicked the + sign and in the window that opened, there's nothing listed there either. Why is installing a printer like operating the space shuttle?

What am I missing?
Thanks

Which OS is supported by the software that you installed. If it does not support MacOS X 10.5.8, then you have to go to Canon's website and download a driver that does.
