You know, there are a lot of comics on here (7... no, wait, 3) that I'd like to print out, but there's just no way to make them come out right without using Photoshop or something, which I can't actually do.
Sorry if this isn't an option either, but on Windows, you can download IrfanView freeware, bring up the comic you want, hit PrintScreen, open IrfanView, select Edit/Paste, outline what you want printed, hit Edit/Crop Selection, save as a .jpg, and/or print.
Or you could just use a Polaroid camera. Or you could just go next door and pull your neighbor's pants down and play with his "wiener." Or you could just go on a hunger strike until your local cable company starts an all "Petticoat Junction" channel.
