No.
>From printf(3):
o An optional decimal digit string specifying a minimum field width.
If the converted value has fewer characters than the field width, it
will be padded with spaces on the left (or right, if the left-adjust-
ment flag has been given) to fill out the field width.
What you wanted is not available in the standard printf(3) model,
since the precision means something else:
o An optional precision, in the form of a period `.' followed by an op-
tional digit string. If the digit string is omitted, the precision
is taken as zero. This gives the minimum number of digits to appear
for d, i, o, u, x, and X conversions, the number of digits to appear
after the decimal-point for e, E, and f conversions, the maximum num-
ber of significant digits for g and G conversions, or the maximum
number of characters to be printed from a string for s conversions.
One might wish that the precision for %d meant the same thing as for
%s, which is what you want, but it doesn't.
