Sepp welcome to the forums.
If your printer is anything like an old i320 I had it shouldn't need one, as Windows 7 is supposed to have a built in driver
for it. If you haven't yet plug the printer in and it should be detected and 7 should install thee driver for it.
The only thing Canon has for it is an add-on module (select Windows 7 from the dropdown), Canon Inkjet Printer Driver Add-On Module
This product is a module that expands the functionality of the printer driver for Canon Inkjet printers as included in Windows Vista and 7.
I never installed it for mine, as I didn't see a need as the control panel for it that Windows installed had just about everything from the old XP control panel.
