Print corresponding elements from two lists

I have two lists xx and yy where

aa = {1, 2, 3, 4};
bb = {12, 13, 14, 15};
cc = {23, 24, 25, 26};
dd = {34, 35, 36, 37};
xx = {aa, bb, cc, dd};
yy = Transpose[xx];


After Transpose,

xx = {{1, 2, 3, 4}, {12, 13, 14, 15}, {23, 24, 25, 26}, {34, 35, 36, 37}}
yy = {{1, 12, 23, 34}, {2, 13, 24, 35}, {3, 14, 25, 36}, {4, 15, 26, 37}}


The goal is to execute a function, Print for example, over these two lists by taking from each list one sublist at a time

zz = Map[Print[#1, #2] &, {xx, yy}];


The object is to get print-out a pair at a time: {{1, 2, 3, 4}, {1, 12, 23, 34}}, then {{12, 13, 14, 15}, {2, 1, 3, 24, 35}}, so on...

 MapThread[Print[#1, #2] &, {xx, yy}];


You can Transpose the list {xx, yy} and Apply your function at Level 1:

foo @@@ Transpose[{xx, yy}]

{foo[{1, 2, 3, 4}, {1, 12, 23, 34}],
foo[{12, 13, 14, 15}, {2, 13, 24, 35}],
foo[{23, 24, 25, 26}, {3, 14, 25, 36}],
foo[{34, 35, 36, 37}, {4, 15, 26, 37}]}

Print @@@ Transpose[{xx, yy}]
