I am getting the following error when I run the code.

`You may need to check the following in the printer's configuration:

what could be the problem?

[thechickenmoo]

Same issue with an MFC-8890DW. It seems to be having trouble decoding the response from SNMP?

Edit:
Further googling, it looks like there was a version change in pysnmp that caused issues for scripts. I was able to install an older version (4.4.8) that worked for this purpose in a "venv" of python that allowed it to run just fine.
I'm running on Manjaro (Arch based) and they don't really keep packages of older versions.

The specific commands I ran (just in case they help somebody else):
python -m venv /home/user1/Documents/Oh\ Brother (I already had an "Oh Brother" folder set aside, so it made sense to just do it there.)
cd /home/user1/Documents/Oh\ Brother
./bin/pip install "pysnmp==4.4.8"
./bin/python ./oh\ brother.py XXX.XXX.XXX.XXX (use the actual IP and the path where you stuck your venv)
