Visualforce allows us to render the page as a pdf thanks to the renderas attribute of the page tag. However, I have noticed some inconsistancies between the pdf render and the vf page render. The inconsistancy I am most concerned about at the moment is font types. I styled an outputtext tag with "font-family:arial;". This works for the vf page, but not the pdf. I have tried a number of methods to change the font in the pdf version but to no avail.

Any ideas?
