FileMaker iOS version adopts AirPrint technology. If a printer supports not only wireless LAN but AirPrint, it can print from FileMaer. But a mobile printer including CMP-20/30 that differs from an inkjet or laser printer does not support AirPrint.

AirPrint needs a function with a heavy load. It is not appropriate for printing receipts because it takes much time even if CMP-20/30 adopts the function.
We recommend an inkjet or laser printer to print from FileMaker.
