I have a Time Capsule and a Canon printer. Basically, I want to be able to wirelessly print to this printer from my MacBook Pro and wirelessly or not from my parent's HP desktop. I plug the printer into the Time Capsule and I can flawlessly print to it from my MBP wire-free. But then my HP can't detect it apparently. It's rather old, I'm not sure if it even has wireless capabilities. Basically, how could I print to this from both machines? Is there like a USB adapter that splits into two, one for the PC one for the Time Capsule? Suggestions?
