So why do conference organizers assume that slides come as ppt or pdf and not as HTML? We usually create slides with #revealjs, nowadays mostly by using #HedgeDoc. Having to upload these slides somewhere as PDF is exhausting, as HedgeDoc does not provide a PDF export for slides and in the current case I have problems both using decktape and with printing the PDF from the browser (which worked the last time I had to do this). See this ticket for context: https://github.com/hbz/slides/issues/59
