Using printf in awk

I have two files $A and $B

$A contains (the operator varies, it could be =, > or !=) Basically I have the awk command working as it should I just want to add the line from $A where it failed

number1 = 460  number2 = 100  

$B contains

number1 453  number2 100  

I have an awk command that compares two files and tells me if the numbers don't match

output=`awk '     {         getline buf <f2;         split( buf, a, " " );           if( $1 == a[1]  && $2 == ">" && $3+0 > a[2]+0 )             printf( "%s\n", buf );         else if( $1 == a[1]  && $2 == "!=" && $3+0 == a[2]+0 )             printf( "%s\n", buf );         else if( $1 == a[1]  && $2 == "=" && $3+0 != a[2]+0 )             printf( "%s\n", buf );       }  ' f2="$B" $A`    echo "$output"  number 453  

I am trying to get this output:

echo "$output"  This is the line that failed: number1 = 460 #coming from $A  This is the correct number: number1 = 453 #coming from $B  

Note that the operators might change to > or < so its important that the output comes from the file
