Nice to be here

I have been using ver 2.02, which I installed from Linux Mint repos.

Now I tried to print a drawing and got only a blanc paper
Is there some way to tell the paper size to the program ?

Then I tried to install ver 2.09 but it went to trees three times.
has the printing been ficed, or is it better to continue with 2.02 ?

You set the paper size in "Current Drawing Preferences". For printing better use "Print Preview". This thread probably adresses your problem too:http://forum.librecad.org/Scale-td5716762.html
If it doesn't help ask again.
2.02 or 2.09 are both outdated. Try to get 2.1.3 installed (or 2.1.2 for Linux).

Thank you. Now I managed to print. The paper size  was custom and the paper width was 2.1*10e5.
Now I go and try to find a new version and give it a try :)
