Based on your numbers they add 10% entropy per character. Which compounds into an increase of 210% over a length of 12 characters. Thus you'd need the password to be at least 3 times longer with only alphanumeric characters to have the same entropy.

no, check your math.

number of characters required for 128 bit entropy password using alphanumerics: 21.49[1]. round off to 22

number of characters required for 128 bit entropy password using all printable characters: 19.5[2]. round off to 20.

22/20 = 110%

There are about 138k printable characters, not 62.
