Thank you for your post.
At this time, multisync and printing is not available in FileMaker Go.
I encourage you to enter these suggestions into our Feature Requests web form at:
These web form suggestions are monitored and read by our Development and Product Management departments where they are then discussed and considered for a future release. Although I could copy your post and paste it into the web form, there are some questions asked that only you can answer.
As a workaround for printing, you can save as PDF, open the PDF file and print.
