List print out

Is there a sensible way to print out a list into a file so that it
appears as columns and rows (spaces and newlines) instead of as a list
with curly brackets.

I'm currently using :

printout[file_,ls_] := Block[{out = OpenWrite[file],
	                lim1 = Length[ls],lim2 = Length[ls[[1]]]},
    	  For[y=1,y<lim2,y++,WriteString[out,ls[[x]][[y]]," "]];

which is not very elegant nor very fast for large lists.
I've tried fancier things like:

printout[file_,ls_] := Block[{out = OpenWrite[file]},

but this puts multiple spaces between numbers so that the columns line

There must be an easy way to do this.  What is it?
