I've got a canon i860 and i'm trying my first go around at printing photos. It has an adapter that's suppose to make it easier to feed in 4x6 blanks, but I'm finding that when I print from iPhoto, it never matches the photo blanks. The i860 did come with a print utility for the printer, but I've not used it, have only tried printing from iPhoto. I find that if i use the print sheet adapter, i get error messages saying the correct paper isn't loaded. if i take the adapter out and simply load the paper normally, it prints, but is askew. What's the trick to getting this guy to print on 4x6 blanks?
