Yes, I've shown the hidden ones and it was not anywhere including
non-PNP drivers.

If the INF file actually have an uninstallation task, try executing the task
from the Command Prompt like this.

rundll32 setupapi,InstallHinfSection DefaultUninstall 132 driver.inf

Double-quote the INF file if the file path has spaces.

I tried the command and also tried replacing "DefaultUninstall" to
"DefaultInstall". Both returns a dialogue window "Installation failed".
So it turns out the driver did not get installed at all. The problem is
the context menu installation do not return any results.

I have also tried "Add printer wizard" (it's a network printer, and "add
hardware from control panel" is only for connected hardware). It shows
error like "the driver is not compatible with current version of Windows
or is not applicable."

I uploaded the file he https://paste.mozilla.org/fUECMyTN
Is there any line saying it is not compatible with Windows XP?
