今天使用python win32com调用金山wps报错，最后找到了解决办法
今天想学习一下怎样用python调用打印机打印文档，网上找了代码如下：
import win32print
import win32com.client
from PIL import Image, ImageWin
#import _imaging
def print_docfile(imagefilename): #打印doc文件
word = win32com.client.DispatchEx(‘kwps.Application’)
#调用word程序
word.Visible = 0
word.DisplayAlerts = 0
#不在前台显示文档及错误，在实际使用阶段可以全部关闭，提高运行速度，但是在调试时打开还是用处挺大的，可以对操作是否实现自己的需求进行直观的判断，比如说我们选中的内容是否已经高亮等等。
doc = word.Documents.Open(imagefilename)
doc.PrintOut()
doc.Close()
imagefilename = ‘d:/dayintupian.docx’
print_docfile(imagefilename)
因为我的机器上只有wps，运行后报错。如下：
*** Remote Interpreter Reinitialized ***
Traceback (most recent call last):
File “C:\Users\Administrator\AppData\Local\Programs\Python\Python37-32\lib\site-packages\win32com\client\dynamic.py”, line 89, in _GetGoodDispatch
IDispatch = pythoncom.connect(IDispatch)
pywintypes.com_error: (-2147221005, ‘无效的类字符串’, None, None)
During handling of the above exception, another exception occurred:

查了资料将“word = win32com.client.Dispatch(‘wps.Application’)”，修改为“word = win32com.client.DispatchEx(‘wps.Application’)”，也不行。然后发现网上的文章说pythoncom接口和wps的版本有关，尝试着修改为“win32com.client.DispatchEx(‘kwps.Application’)”，结果报错信息发生了变化如下：
Traceback (most recent call last):
File “C:\Users\Administrator\Desktop\printfile1.py”, line 16, in
print_docfile(imagefilename)
File “C:\Users\Administrator\Desktop\printfile1.py”, line 12, in print_docfile
doc = word.Documents.Open(imagefilename)
File “
pywintypes.com_error: (-2147352567, ‘发生意外。’, (0, ‘Kingsoft WPS’, ‘文档打开失败。’, ‘’, 3010, -786427), None)
个人感觉有戏，感觉接近成功了，继续在网上找资料，最后有大牛说是文件需要绝对路径，于是将文件路径修改为绝对路径**imagefilename = r’d:\dayin\tupian.docx’,**终于解决问题，可以正常打印。特此记录。
