|SAM4s SPS-520F cash register|
If you need a journal or audit tape with the 530F then you can turn on the electronic journal which prints to memory instead of a paper.
Other then the printer difference the two machines are the same. They both use the Datacap Twin Tran for credit card interface, they both can interface to computer, kitchen printer, kitchen video, scale and more.
