Hello! Thanks for the feedback.
You can print charts when using the desktop application. We have no plans to add printing of charts/plates to any other platform.
Regarding the flightplans, we currently support saving your SimBrief OFP, if available. These can then be printed! We opted to not include a print function due to the reasons outlined here: Print SimBrief OFP - #2 by skysail
In the future, when something like VFR Navlog is available, we surely will make that printable in some form as well!
Kind Regards,
Malte
