[GitHub]: ActiveState/code - (master) code/recipes/Python/305690_Enumerate_printer_job/recipe-305690.py (that raises ctypes.ArgumentError in your case) is ancient, some parts of it only worked by luck, and some of them never worked (as the flow didn't reach them).
I submitted [GitHub]: ActiveState/code - Fixes and updates which addresses the major problems (there are some left, but the code is working).
Starting from that, I tried to tailor it for this question, and address the items (partially at least). Since the question is tagged for [GitHub]: mhammond/pywin32 - pywin32, I used it in order to have (much) shorter (and Python friendlier) code.
