Looks like you tried to print the Quote Studio interface itself. To print or save a polished client-facing PDF, use one of these:
From a quote you just generated, click the gold PDF button. The customization modal opens with a live preview — use the Print / Save PDF button at the bottom.
From the Saved tab, find any quote and click Print PDF on its card.
Both flows open a clean, branded quote in a new window with proper print styling. That window is what you want to print.
