SMARTFORMS - White letters on black back ground

Hello Experts

I am creating a smartform that has white text and black back ground. In print preview it looks perfect but when I send the form to the printer the white letters do not appear, it is all black. I did a print screen when it was in print preview mode and it printed fine on the printer, white letters on black back ground. What am I missing to get it to print via smartforms, something in the CALL FUNCTION?

CALL FUNCTION fm_name

control_parameters = gs_control_param

output_options = ls_output

is_packlist_data = i_packlist

zle_ps_header = ls_header

user_settings = space
