Here is how I change the Virtuaizer demo to try to print directly.
But it is sensible the same :( The main() is existed before the print is
relly lauched by the system :( (I use linux debina with cups) CUPS is
launched (there is a job icon into gnome) only when the main() is
finished.
Is there a way to print before ?
