Thanks for picking this up, @AnubhavMaheshwari. The print CSS and the beforeprint/afterprint state handling look good. A few things before I can merge:

• Line endings: report.js was converted from LF to CRLF, so the diff shows +454/−277 when the real change is about 177 added lines. Please restore LF (git config core.autocrlf input, then re-checkout and reapply your changes) so the diff is reviewable.
• Test result: the PR description still has the "[Add the actual test result here]" placeholder. Please fill it in with the real result.
• Command: .\mvnw.cmd test is Windows-only. ./mvnw test is what CI runs.
• Manual check: please add a short note, or a screenshot of the PDF output, showing a report with a collapsed group and a failed test printed with its stack trace.

Happy to re-review as soon as these are in.
