    this does not work properly only the file reader bit does, no printer options is ever displayed
    Where does the code call any printer methods?

    Do you know how to call a method?

    java.lang.NullPointerException
    at java.text.AttributedString.<init>(AttributedString .java:127)
    at PrintText.<init>(PrintText.java:14)
    There is a variable with a null value when line 14 is executed.
    Look at line 14 and find the variable with the null value. Then backtrack in the code to see why that variable does not have a valid, non-null value.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    Now look at line 109 the same way you looked at line 14 in the previous error.
