Last part SOLVED!!
Robin, it was libgnomeprint-2.18.0 doing the portrait orientation of
the contents of html when printing in landscape. I emerged 2.12.1
and it worked correctly. Reinstalled 2.18.0 and it is doing it again.
Guess have to write a gnome bug report now.
I have another problem with the printouts, but I will write a new
thread for that one.
Seems that everything will be okay now and maybe can get
on with finishing my application.
Thanks a lot!!!!
Dave
