Print Slide Blank on Edge

DShaw's checks are the right first moves. One more angle on the Edge-only part:

Review 360 serves your course inside an iframe, and Edge's print pipeline is pickier about printing from frames than Chrome's. I was debugging print-from-Storyline in an iframe on another thread this week and ran into exactly that kind of browser-specific weirdness.

Two tests that would narrow it down:

1. Publish the same project to Web (local files) and open it directly in Edge — not through Review 360. If it prints fine there, the problem is the Review 360 frame, not your slide or your trigger.

2. Run DShaw's Ctrl+Shift+P test. If the system dialog prints fine, it's Edge's preview renderer, not your content.

Post back what those two show — the fix depends on which one fails.
