Avoid print dialog when printing alv list ?

hi,

i have a z-report with alv grid display. when printing the alv i get the print parameter popup (see screenshot).

i know how to set print parameters for ALV......but how can i avoid and hide the print dialog popup ? so that the list is printed with pre-defined values in print parameters ! that means that user should NOT be able to change it and therefore he should NOT get the popup.

br, Martin
