As mentioned, if you do not want the interpolation, escape the symbol...

    print "\%dsadada ssadasd\n";
    print "\@dsadada sdsadasd\n";
    print "\$dsadada sdsadasd\n";

OR, use single quotes...

    print '%dsadada ssadasd' . "\n";
    print '@dsadada sdsadasd' . "\n";
    print '$dsadada sdsadasd' . "\n";

Both of which will print:

%dsadada ssadasd
@dsadada sdsadasd
$dsadada sdsadasd

What exactly do you want it to print instead?
