Image failed to load:

Error message

Image failed to load:

What it means

Warning logged in `waitForImages` (used by printToPdf) for each image whose load failed — `img.complete` is true but `naturalWidth` is 0, meaning the src could not be loaded (broken URL, network error, or CORS). Printing continues without that image; it is a diagnostic, not an abort of the print flow.

Solutions

1. Check the image URL is reachable and CORS-enabled.
2. Retry printing after the image loads.

When it happens

Trigger: Triggered during print-to-PDF when an image element has completed loading but naturalWidth is 0, indicating the image resource failed to load.

Common situations: Occurs when printing a page whose images are broken or unreachable, so they are missing from the PDF. Check the image URLs and network before printing.
