Ah , Keith , you were asking about 6x9 paper, so this makes sense now. 6x9 is the favoured size of Event Photographers, precisely becuase they use dye sub printers.
You can hire them out , there are at least 3 sources for this. No doubt some experienced event guys will be on to answer more of your queries.
If you are going to do this kind of work more regaularly , you shoud consider buying. It makes more sense.
There are several brands of dye sub printers on the market - DNP, Mitsubishi, FujiFilm, HiTi, Kodak and Sony.
Event Photography has been discussed many time on TP, including the hire or purchase of equipment , so worth checking the archive.
