You've already been advised to use:

for_each(c.begin(), c.end(), bind(newPrint, _1, ref(out)));

Remember, for_each only passes one argument, you can't use _2 to select the 
non-existent second one, and your noncopyability problem is solved by using 
boost::ref. You even asked "is there an equivalent to boost::ref" in your 
original post. Yes there is, it's called boost::ref. :-)
