The text content of an academic poster will generally be very important, so you need to make sure it is easily readable, and helps viewers follow the flow of ideas.
Your final poster will need to be printed on a large-format printer; this service can be provided by Design & Print Solutions, who are equipped to print in excess of size A0.
Printing is not done directly from a PowerPoint file. You need to export the poster to PDF format, ensuring you maintain the high resolution for your images.
Check through your poster before exporting. If possible, get someone else to read through it carefully — a fresh pair of eyes is better at spotting spilling mistokes.
The PowerPoint File tab/menu includes the option to Save or Export as a PDF.
If you choose Export:

Check your PDF thoroughly. If you have used transparency settings and/or drop-shadows, this is the point when you may notice some shapes or images not rendering correctly.
If shadows or transparencies are not appearing correctly on your PDF, you could try using a PDF Print method instead:
Hopefully this will solve the issue, and increasingly such problems are few and far between, but in some cases the only 'cure' is to simplify your use of effects.
Before you commit to a commercial full size print, you may want to print a test version to see what it looks like on paper. It's easier (and more accurate) to do this from an exported PDF rather than directly from PowerPoint.
You can get a reasonable idea of what your poster looks like by printing a scaled-down version at A3 size. To do this, you'll need to print from a computer with a 'desktop' version of Adobe Acrobat PDF Reader (or similar). These instructions assume that's what you're using.
Obviously you'll need to use a bit of imagination to imagine what the poster looks like at its proper size. A1, for instance, is four times the size of A3.
If you want more of an idea as to what your poster looks like at actual size you could use the tiled printing options in Adobe Acrobat PDF Reader (or similar): This will print your poster on several sheets of paper which you can then piece together like a jigsaw. Again you'll need a 'desktop' computer from which to send the print job.
Sometimes it can be useful to just get a full-size view of a section of your poster. There are two methods you could use:
