printing email

My Deskjet All-In-One 1050 J410 series printer will not print e-mails when I right click and select print.

What it does do, is print what appears to be a 2nd page with a header received from yahoo.com from the following address:

https://ca-mg6.mail.yahoo.com/neo/launch?.[partner=rogers-acs&rand=1oflmr863hfaa 

When i right click on ducumente other than email I have no problems.

Thanks
