There some thermal dye sublimation printers targeted at the home market for making 4x6" prints. The cost-per-print is pretty hideous compared to a local store's photo dept. or online photo printing services, but the quality is pretty good and the units seem to get good reviews. I've seen them used for print-on-demand at events (think "photo booths", etc).
