I was recently asked how to print a specific frame in Blackboard (e.g. a list of discussion board postings or a content area), either to PDF or to a printer. A bit of Googling turned up this handy guide from Milwaukee Area Technical College Facultynet that walks you through the process of doing this via Firefox on the PC. I tried it on Firefox on the Mac with positive results. As a bonus, it shows you how to select specific blocks of text/images from a page and print just that (or paste it into a Word document).
