A long time ago, my team was assigned new User Story what is called print preview. At scratch we think that the function is so easy. But, at the end of the sprint we couldn’t complete this feature.
We fail because the solution print preview with html + CSS couldn’t support the rich layout as customer expected. We just think that the print preview is normal, many platform did that before, CSS for print is powerful to make rich layout. But in actual CSS for print so poor and many style cannot apply.
After that, we switch to server side rendering solution: convert the page to pdf and anything is good.
Did you have another case study for print preview ?
