Vitaliy,
Wonderful extension for presentations. We are running into issues with printing when scaled=true. When we click the printer icon, the page itself loads nicely. However when you ctrl+p to save to PDF per these instructions http://wiki.4intra.net/S5SlideShow#Printing_and_PDF_export scaling becomes a huge issue. Words become massive and span multiple slides. We've tried multiple browsers.
Thanks much,
Erik Biegert
