[GitHub]: ActiveState/code - (master) code/recipes/Python/305690_Enumerate_printer_job/recipe-305690.py （在你的情况下引发 ctypes.ArgumentError ）是古老的，它的某些部分只是靠运气起作用，而其中一些从未起作用（因为流程没有到达他们）。
我提交了[GitHub]: ActiveState/code - Fixes and updates，它解决了主要问题（还有一些问题，但代码正在运行）。
从那开始，我尝试为这个问题量身定制它，并解决这些项目（至少部分地）。由于该问题被标记为[GitHub]: mhammond/pywin32 - pywin32，因此我使用它是为了获得（更）更短（并且Python更友好）的代码。
