No, you can’t. You cannot hack it even if the printer is connected to a computing device, if the computer is not connected to a network. An attacker can still sniff a wireless connection between a computer and a printer, even if no connection to the outside world is in place.

Basically, no, flatbed scanners don’t remember old scans. A flatbed scanner sees a lot of incoming data (the pixels) and outputs them all on whatever communication medium it has (say, USB). RAM is used as a buffer between the two.

With a standalone printer, it doesn’t retain anything, but an all-in-one might have saved documents, scans, print logs or fax logs. To do a basic reset, turn the printer ON, unplug it for 15 seconds and then plug it back in. That should get rid of everything.

Yes, it is possible. This below scenario is for basic printer. Each printer has network connectivity and they support firmware upgrades. If the firmwares are not signed or signing material compromise or vulnerability In that area can help a attacker push malicious upgrade which can have virus inbuilt.

You just have to adjust the security settings on the printer to do that. Just to to Devices and Printers, right click on the unit, go to Printer Properties and under the “Security” tab you can restrict users on the same network.

Botnet attacks− Hackers can connect your printer to a botnet, which can be used to steal your data and carry out cyber attacks. Malicious device malfunctioning− Some hackers breach printers simply to wreak havoc. They can command your printer to randomly print weird files or shut off, among other malicious actions.

Most Android phones have printing capabilities built in, but if your device isn’t giving you an option to connect, you’ll have to download the Google Cloud Print app. They can also connect seamlessly to your Apple or Android device for quick and efficient printing.

Sorry no there is no password protection for the printer. Connecting to a public network will allow everyone to find and use your printer. Use a USB cable for security. Or you can use Wireless Direct, but you can’t be on the Internet and print at the same time.

Completing the Print Job at the Printer

1. From the main menu, select “Printer.”
2. Touch the “Print Jobs” tab, then “Locked Print Jobs” from the menu on the left.
3. Touch the row displaying your print job, then “Print” on the touch-screen.
4. Enter the password you used to protect the job (not your NRAO AD password), then “Ok.”

Here’s how.

1. Limit or disable network printing.
2. Secure your printing ports.
3. Use a firewall.
4. Update your printer firmware to the latest version.
5. Change the default password to a strong passphrase.

One reason why your printer might be asking for a password is because it is a wireless printer attached to a Wi-Fi network. Rather than connect to it with an Ethernet or USB cable, your computer might be connected to this output device via Wi-Fi.

I suggest you to try entering 12345678 as the password. This is the default password for wifi direct.
