Setting Paper size in data reports

Hello Everyone
I am using Data reports in my project. I want to take the print out of the report, on the Continuous Computer Paper(using dot matrix printer). I am unable to set the page width of the report to suit this dimension. Can anyone kindly tell me how can i do this?

Thanks in advance
Regards
