We have had the Sony DPP- EX5 for a number of years and it has proved itself to be a very good quality printer indeed. THe DPP EX5 has now been replaced by the Sony DPF85, which the same but for its name and that it now lies flat rather than on its side.
The printer itself is a thermal printer, which prints high quality photos on proper printer paper. The prints themselves are very good quality and the colour is layered on and laminated in a very similar way to photos which are produced in a lab. The result is fantastic and is much better than any photo that is printed onto normal printer paper or onto any other photo paper that I have seen.
It is extremely handy in that it connects via USB. It can also take SD cards however, I have not tried this option. The printer has a simple menu which you can use if you wish or follow the printing instructions from windows photo viewer. You can then print borderless or bordered photos. The bordered photo option is why I chose the printer in the first place as I feel that it offers a smarter print finish. The printer itself is very small and can be either stored with the pc or packed away smartly when not in use.
The downside with this printer is the printer cartridges. Sony have very handily designed it so that the cartridge lasts exactly the same length of time as the printer paper. You then purchase a pack of paper and a printer cartridge. This is an excellent idea however, the cost is prohibative. It costs £39 for a pack of 75 photos and cartridges (this is 3 packs of 25 and 3 cartridges). Therefore the cost per print is quite high. I have bought the paper cheaper in teh USA however, this is only because I have family who can bring it back with them.
Despite the cost however, I do continue to keep the printer and purchase the paper. I only print a selective few photos from each holiday and store the many thousands of others on the PC. THat way I keep the costs down and have a lovely album to look through.
