- I suggest that you first save pdf files to your computer, then view them.

- If your file is too big and the printer has small memory, printer may print 1-2 pages or nothing.
1. Find another printer with larger memory.
2. Turn off spooling on your printer.
3. Print all pages one by one, especially those without figures. Then print the pages with figures as images (a check box in the printing dialog box).

Thanks to Alex Serrano and Asif Khan for the info.

- To print several pdf pages on a single paper page, click on Print then Properties in your Acrobat Reader. You can now set the number of pages per paper page to 1(default), 2, 4, 8 or 16. This should be handy printing the slides.
