Hi
Please could someone on the Italian Users Mailing List (or equivalent) please pass this question on to them so that Manuel can ask the questions in his own language. I am only guessing he is Italian from his email address ".it".
Manuel;
You can create a Pdf directly from Draw. You can probably print Pdf by just double-click on the file to open it and then choose
File - Print
You don't need "freeware virtual pdf printer" and freeware is unlikely to work in openSuSE anyway. To create a Pdf from Draw just use
File - "Export to Pdf"
Even easier is to ignore Pdf and just print directly from Draw. In Draw it is just
File - Print
A brochure is usually an A4 page on it's side (landscape mode rather than portrait) and then either folded in half or into 3. When folded into 3 it's often called a "gate-fold leaflet". When folded in 2 a single A4 page becomes A5 but now has 4 sides (front, back and 2 in the middle).
To do either properly is best done using a template or careful layout. I did an imperfect one just using
Format - Columns
So that the A4 page had 2 columns, one for each side. First column being the back page, 2nd being the front and on the next A4 page it was page 2 and then page 3. So it all flowed neatly from the first page, except the final page which i had to cut&paste from the end to put it before page 1. That was "good enough" at the time but many people have much better and often easier ways.
Good luck and regards from
Tom
