The scenario is like this: there is a wifi printer connected to a router (wpa2 encryption). The printer has its own ssid which is open (no password) and the webpage is without password too. I can see that the printer is connected to xxxx ssid of a router but the password is not shown. The printer is an HP LaserJet. Is there any way to extract plain text password of the wifi router? I already tried some tools (like PRET) on parrot but no luck. It only has 3 open ports (443, 80, 8080). No ssh. Any way to exploit it? Maybe js or exporting filesystems? For sure the password is stored somwhere inside printer. Thanks in advance.

If you did a standard deauth attack while sniffing for handshakes, you'd know that there's at least one client to reconnect.

As Fallen Archangel said but then you need some cracking.

Another option, if this is even avaliable, is to backup printer settings and try to do some magic with backup file
