Thank you Vald.  I am actually trying to understand why
Firefox on linux does not print (both using printer or the Canvas API)
any flash plugin content, but on
windows it works.

I am wondering if the fact that FF3 moves to cairo will fix this
problem. But from my testing with FF3 on linux, that does not fix

I am looking if there is a solution for this problem.

Thank you.
