I’ve been looking to find a way to export my project to .pdf without the resource chart. I haven’t been able to find a solution within GanttProject as of yet.
Do you mean that you want whatever GanttProject exports to PDF, just without a single page?
Actually what I’m looking for is the ability export the project in .pdf without showing the Loading / Cover Page… jus the actual GANTT chart itself. If there was a selection box / dropdown to allow users to save as .pdf only the pages they want it would be very helpful 
If you need a Gantt chart only, you can use PNG export.
Relevant enhancement request in the issue tracker:
Hi, not sure if this is helpful, but once you make a full pdf export, you can print the pages you need into another pdf file.
