Steps to verify
- Print a sample at final size.
- Test from the real position with different phones.
- Compare image and print changes separately.
How to interpret the result
If the screen original scans but the print fails, compare production conditions before the URL. Review the white border, pattern clarity and obstruction.
Deciding what to do next
One physical size cannot be assumed to work in every situation. Retest after changing reflections or folds and inspect the reached page as well.
Feature scope
Generate PNG codes for HTTP/HTTPS URLs without visiting destinations. This is not a text or Wi-Fi generator; test the final printed material separately.
