Print flash from Firefox not working -

[Bob Goodwin]

In Fedora 19 I am unable to print flash crossword puzzles from firefox. 
The work around is always the same, use Seamonkey instead which works as 
expected. The problem with Firefox is that it stops at the point where 
the box comes up for selecting the printer, no printers are offered! The 
same box produced in Seamonky lists the available printers.

Does anyone know of a work around or fix?
