infoodle sometimes generates PDF documents.
Some browsers will display the PDF within your browser, which is nice - but it's not always obvious what you do next.
The trick is finding where the PDF icons are - they are shown by moving your mouse towards the bottom centre or left of the screen. Doing this will reveal a strip of icons.
The icons include print, save, zoom in and out
If the PDF is not showing at all - it maybe your browser configuration.
If you are having issues printing a PDF from the browser within Internet Explorer - it maybe your settings.
