I have my PowerMac plugged into my Microsoft router/wireless hub via Cat5. I have the PowerBook running wirelessly through the hub. All is well. With my printer, it is plugged into my PowerMac via USB. Is there any way to access the printer with the PowerBook? There is no USB connection on the hub to plug the printer into to make it a network printer. I'm hoping to not need to buy something like Airport Express just to be able to network the printer. TIA.
