I move around from office to office and would love to be able to use their local printer on occasion rather than carry my own or send things to the local Kinko's Office facility and pay per-page. I know the Mac can see local printers, but how do I tap into that for my own printouts?

This is kinda complicated, but I have a cool new Samsung ML-25x series printer hooked up to my Windows computer and it works great. Really happy with it. My boyfriend has a Mac laptop and when he's at my place he wants to be able to print on it too, without emailing me the printouts beforehand. I figured out how to "share" the printer on my XP system, but he can't figure out how to hook it up wirelessly on his MacBook. Tips? Hints? Thanks!

I move around quite a bit as a road warrior and though I don't often need to print, sometimes being able to produce a hard copy is definitely helpful. Problem is, I don't want to bother people in different temporary offices with configuration details: I'm running Mac OS X Snow Leopard on my MacBook Pro, is there some easy way to add printers on the go?
