ksh + printf stat gap of print

I need to print the following values with printf as the follwoing around like this:

printf "[date +%d"/"%b"/"%G"-"%T] [WARN] $PARAM1 $PARAM2 $PARAM3

The required output:

[02/Jun/2010-11:08:42] [WARN] val1....val2...val3

the gap between val1 to val2 and from val2 to val3 must be const gap not depend the length of the values

You can specify field widths for printf. Here are examples of printing numbers (spaces or zeros as prefix) and strings (left or right justified):

$ printf "[% 10d]" 1
[         1]

$ printf "[%010d]" 1
[0000000001]

$ printf "[%10s]" test
[      test]

$ printf "[%-10s]" test
[test      ]
