There must be some decent printers left in Norwich, but as I print my own I have no knowledge of them. Norfolk Camera Centre in Dereham do have a print machine for normal stuff, and also have (I think) an Epson R2400 "upstairs" for larger stuff. If they are not too busy they will do it while you wait. I know nothing off the cost - I have just seen other togs bring their cards in and get pics straight away.
