The main one is setting functions argtypes and restype. Modern Python versions raise an exception:

Traceback (most recent call last):
 File "..\..\GitHub\CristiFati\code\recipes\Python305690円_Enumerate_printer_job\recipe-305690.py", line 194, in <module>
 prt.EnumJobs(pJob, prt.pcbNeeded)
 File "..\..\GitHub\CristiFati\code\recipes\Python305690円_Enumerate_printer_job\recipe-305690.py", line 164, in EnumJobs
 ret = ws.EnumJobsA(self.OpenPrinter(),
ctypes.ArgumentError: argument 5: <class 'OverflowError'>: int too long to convert

preventing funky Undefined Behaviors: [SO]: C function called from Python via ctypes returns incorrect value (@CristiFati's answer).

I'm not sure how some of the code worked (if it did). Still uncertain about ReadPrinter part.

There are other problems to be addressed:

  • Some harcodings (int values)
  • Error checking (via GetLastError)
  • Some structures are out of date
