Hi,
For in-browser viewing, DSpace 7 or 8 has two main options:
* The "Media Viewer" which can support any image/video files (any with MIME Type starting with "image/" or "video/"). See
https://wiki.lyrasis.org/display/DSDOC7x/User+Interface+Configuration#UserInterfaceConfiguration-MediaViewerSettings
All other formats, DSpace will just send directly to your browser when you download the file. However, depending on your browser's settings, some of these file formats may still open in your browser (if the browser knows how to open them). For instance, many browser's will open PDF files automatically, but they may only download Word files.
I'm not aware of any way to do "bulk selection of records for printing" in DSpace. I'm unclear what that references though.
