I have bought the HP Deskjet Plus 4100 printer and initially set it up, was working all fine. But recently when I have changed the Wi-Fi password, it stopped working . Not able to print, scan and copy files.

@Chandra_Sekhar Welcome to HP Community!
I understand that the HP Deskjet Plus 4100 not working after resetting the Wi-Fi password.
Please perform the hard reset and check.
Turn the printer on, if it is not already on.
Wait until the printer is idle and silent before you continue.
With the printer turned on, disconnect the power cord from the rear of the printer.
Unplug the power cord from the wall outlet.
Wait at least 60 seconds.
Plug the power cord back into the wall outlet.
Reconnect the power cord to the rear of the printer.
Turn on the printer, if it does not automatically turn on.
Wait until the printer is idle and silent before you proceed
Please refer to the below link to troubleshoot the issue.
