[Python] 프린터 정보 얻기 - win32print

파이썬으로 현재 컴퓨터에 연결되어 있는 프린터 관련 정보를 얻어 보자.

 

먼저 아래와 같이 win32print 모듈을 다운받기 전에 pip 버전을 확인하고 가상환경 설치파일 버전도 확인하자.

필자는 F:\python_win32 폴더를 미리 만들어 두었다.

 

F:\python_win32>pip3 --version
pip 20.2.3 from c:\users\wonpa\appdata\local\programs\python\python39\lib\site-packages\pip (python 3.9)
 
F:\python_win32>virtualenv --version
virtualenv 20.4.0 from c:\users\wonpa\appdata\local\programs\python\python39\lib\site-packages\virtualenv\__init__.py

 

# 가상환경 설정

printer_venv 라는 이름으로 가상환경 설정한다.

F:\python_win32>virtualenv printer_venv
 
created virtual environment CPython3.9.1.final.0-64 in 6942ms
  creator CPython3Windows(dest=F:\python_win32\printer_venv, clear=False, no_vcs_ignore=False, global=False)
  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=C:\Users\wonpa\AppData\Local\pypa\virtualenv)
    added seed packages: pip==20.3.3, setuptools==51.3.3, wheel==0.36.2
  activators BashActivator,BatchActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator

 

# 가상환경 실행하기

F:\python_win32\printer_venv\Scripts>.\activate.bat

 

그런다음 dir 을 눌러 현재 작업폴더 위치를 확인한다.

print_test1.py 가 필자가 만든 프린터 정보얻기 예제 파일명이다.

이제 win32print 라이브러리를 이용하기 위한 준비과정은 끝이 났다.

본론으로 들어가서 프린터 관련 정보를 땡겨보도록 하자.

properties["pDevMode"] 가 핵심이다. 

각각의 속성이름을 바탕으로 프린터 고급 세부 설정내용을 살펴 볼 수 있다.
