We do plan to add a UI for configuring page orientation and/or width to hopefully address this. No timeline yet but it should be in our queue. Do you mind submitting this as a support ticket via Rollbase.com? We'll then track it as an enhancement.
Thanks Matt, I will do that!
Marking as In Progress
This should now be addressed in 4.06 via changes in the way we generate HTML for PDF rendering. Let us know if you still run into issues with 4.06 or later.
