Font not loading in live preview

Common causes

1. Content Security Policy (CSP) blocking Google Fonts. Check your theme.liquid or Shopify's Content Security Policy — font-src should include https://fonts.gstatic.com.
2. Font file failed to load. Open browser DevTools → Network tab → filter by 'font' → look for red 4xx/5xx status.
3. Ad blocker or privacy extension blocking Google Fonts. Test in incognito with extensions disabled.
4. Custom uploaded font missing license verification. Print It My Way accepts custom TTF/OTF/WOFF uploads but requires you have a commercial license.

Verify Google Fonts CSP

Print It My Way loads fonts from fonts.googleapis.com (CSS) and fonts.gstatic.com (font files). If your Shopify theme or CDN has a strict CSP, add both origins to font-src and style-src.

Fallback behavior

If a font fails to load, Print It My Way falls back to a system serif or sans-serif. The customer's chosen font name is still stored as a line-item property on the order, so your production team knows the intent — the print file is generated with the correct font server-side even if the preview fell back.
