My printer is HP LaserJet Pro MFP m126nw. After setting up my printer in Ubuntu 20.04 (using HPLIP 3.20.3), when I tried to scan, it was mentioned that driver plug-in installation is required. When I try to install the driver plug-in, it simply doesn't install.
Then I used the terminal and typed this command:
hp-plugin
The output was:

I messed up the pre-installed Python in my device.
An excerpt from one of my questions (in which I explained about the Python issue):
I guess Python 3.8.2 was pre-installed with my Ubuntu installation. I wanted to upgrade to Python 3.8.3. So I followed the instructions mentioned in this website Install Python 3.8.3 in Ubuntu 20.04 LTS - TechPiezo.
At the end of the article, two suggestions were given. First is to replace (or overwrite) already installed version 3.8.2 of Python; second is to install Python v3.8.3 alongside the Python v3.8.2. I followed the first option.
With Kulfy's help (link to Kulfy's answer), I hopefully reverted back to the pre-installed Python 3.8.2.
Now, the output of hp-plugin
is:
