Right, using the PC as a print server is unnecessarily complicated.
I think my Expert did it that way because for some reason he could not get the "regular" way to work. It took him over an hour to get the iMac to print on the network printer.
System Preferences -> Print & Scan, then hit the little "+" button on the lower left. Your Mac should hopefully discover the printer on its own, and at that point you just have to follow the various dialogs where you click "okay".
I'll try that and see what happens.
