I am getting an 24" iMac and will order it with the new printer promotion, which is a $100 rebate. I am looking for a good all-in-one. Don't really need a fax, but scan, copy and of course good B&W and Photo printing. Don't need camera direct or card printing or viewing screen. Will edit in iPhoto first. 1. Does anyone have any recommendations or bad experiences on either of the following printers? Will hook up through Airport Extreme for wireless from iMac and 12"PB. Also, I do like the idea of the document feeder for scanning multiple pages to a single pdf. Canon PIXMA MP530 Canon PIXMA MP830 HP Photosmart C4180 HP Photosmart C5180 2. Does anyone know if the promo works for edu purchases?
