printing from ipad too large on p1102w

All my printing from the IPad print out too large compared to the print from my Win7 PC.

E.g. If I print an email from my WIn 7 PC to the HP P1102w result normal - 1 page.

The same email printed from my Ipad to the P1102w prints a much larger font and runs to two pages.

Any ideas how to rectify this?

Thanks

James
