The issue describes a bug in the `print` method of Jimp when `alignmentX` is set to `HORIZONTAL ALIGN RIGHT`. The text starts at `maxWidth` instead of wrapping from the right edge. To fix, examine the text layout logic in the `print` function, likely in `src/index.js` or similar. Look at how the `maxWidth` parameter and alignment flags interact during text wrapping. There are no linked PRs or comments, so the fix requires independent investigation of the font rendering code. Consider writing a test case that reproduces the issue before making changes.
