Something that you can try with the report, as a workaround, is to click on 'Save' instead of 'Print'.
Save the report as an HTML file. Be sure to retain the .html file extension when naming the report file.
You can then open the HTML report file in a browser, a word processor or a spreadsheet program and print the report from within one of those environments. You'll likely have a lot more flexibility in printing from within either of those programs.
Saving report to an .HTML file does the trick for me.
The Firefox web browser does a very nice portrait printout.
