printf returns 1 for a successful print, which is what you say happens. You probably want sprintf (note leading 's'), which returns a string.

Update: 

>perl -wMstrict -le
"my $line  = 55473;
 my $line2 = sprintf '%#x', $line;
 printf qq{\$line  is '%#x' \n}, $line;
 print  qq{\$line2 is '$line2'};
"
$line  is '0xd8b1'
$line2 is '0xd8b1'
