TurboPrint can be bought
here. CD availability is new - it was sold only on floppies when I bought it a couple years ago.
Another driver package to look out for is StudioII by Wolf Faust. He also has a free set of Canon drivers (see CanonDisk on Aminet) that has pretty good support for late 90s/early2000s Canon printers.
There are also scattered individual drivers kicking around Aminet.
