This page is empty because you cannot yet set up specific printers for specific reports. We are working on solving this.
In the meantime, when you want to print a report you have to download the report as a PDF document first by choosing the Send to button. Then you select the type of file to download the report as, and here you should pick PDF Document. Now, you can either open the PDF document right-away and print it, or save it and print it later.
