Well, depends, if you have a postscript printer of one that does postscript for you like printer drivers in linux, then something like a simple lpr of a short postscript program would print that.

e.g.
%!
72 2.54 div dup scale
.5 .5 translate 0 setlinewidth
0 1 20 {0 moveto 0 28 rlineto stroke}for
0 1 28 {0 exch moveto 20 0 rlineto stroke}for
0 1 28 {0 1 20{1 index 2 copy add 2 mod 1 eq{0.1 0 360 arc fill}{pop pop}ifelse}for pop}for
