Is it possible to enable a landscape designed form with Anoto functionality using the FDT?
Yes it is possible to enable and produce forms in landscape mode, but it is not recommended to mix portrait and landscape pages in one form design.
If you are to print a form in landscape orientation you must either enable the print parameter “Page Size” in the Forms Design Tool, or apply the switch "--pagesize 1" using the Paper SDK. An alternative is to set the printer to print in landscape mode.
