Owing to the use of' elsif' in the auto-port-detection bit in printtool, only one port will ever be detected. The' elsif's need to change to' if's.
and actually, they should be cascaded, because with the 2.2 kernel, you'll never find a lp1 without an lp0...
Fixed in printtool-3.42-1, which will be in the next Raw Hide release.
