I haven't read anything I would disagree with in this thread. I get good 4'x 6' from 350 kb or larger jpeg files. This from an HP 722 which is antique by todays standards. I have seen good 8'x 10' from 1.1 meg files, though I would not try it for commercial or show purposes. Either HP or Epson will sell you top of the line for $300 if you can stay under 8.5' x 11'. Paper and ink are commodity items and are open to shopping. Though the printer manufacturers don't want you to use alternate sources. They set their paper and inks to match a particular standard. The printing does present another facet and that is color rendition that is true to the eye. You must calibrate the screen and the printer to get consistent results. The screen is light on phosphor, the print is reflected light from the room/sun source. It is all about what the eye tells the brain.
