How to change print width in ngspice

If output of print command is longer than 80 characters, ngspice will wrap lines at 80 characters and add new table header. To prevent it use this command:

.control
set nobreak
set nopage
set width = 99999
.endc

It took me 1 hour to find it because ngspice documentation states to use ".with out = 99999" which actually does nothing.
