Here's your first mistake:  you need to get the result of that call.
Try:
       stdprn = io.open('stdprn', 'w')

Note that (1) You may have just created a file named stdprn.
           (2) You need to close that file bwhen you are done.
           (3) A final end-of-line is traditional.
           (4) You could give us a clue about your operating environment.
               (To wit: os, version, python version)

A printer is nothing Python has or controls, it is  a standard thing for
a computer system, so details about your computing environment are
necessary in order to give you good advice.
