All python libraries that implement the Internet Printing Protocol (IPP) do not seem to work under python3.

Here is what I've tried so far:

• pkipplib
  

  import pkipplib.pkipplib        # installed via pip

  Leads to the following error:
  

  Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/home/user/.local/lib/python3.6/site-packages/pkipplib/pkipplib.py", line 308
          raise KeyError, key
                        ^
  SyntaxError: invalid syntax

• pyipptool
  

  import pyipptool        # installed via pip

  Leads to the following error:
  

  Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/home/user/.local/lib/python3.6/site-packages/pyipptool/__init__.py", line 1, in <module>
          from .config import get_config
      File "/home/user/.local/lib/python3.6/site-packages/pyipptool/config.py", line 1, in <module>
          import ConfigParser
  ModuleNotFoundError: No module named 'ConfigParser'

I use python 3.6.7 on linux.

Thank you and best regards

You could work with CUPS directly:
https://pypi.org/project/pycups/

#!/usr/bin/python3
import time, pprint, cups
  
conn = cups.Connection()
printers = conn.getPrinters ()
pprint.pprint(printers)
print()
  
printer = conn.getDefault()
print("Default1:", printer)
  
if printer == None:
    printer = list(printers.keys())[0]
    print("Default2:", printer)
  
myfile = "./test.txt"
pid = conn.printFile(printer, myfile, "test", {})
while conn.getJobs().get(pid, None) is not None:
    time.sleep(1)
#done
