Printing Troubleshooting
When printing pdf files of posters to certain printers, some problems have been found to occur.
One remedy is to locate any "Advanced Printing" options and select "Print as Image" if you can.
Also, do not have your pdf viewing software reduce the image to fit printer margins - there is already sufficient blank space around the edges for this not to be a concern.
