Model: Deco M9 Plus  
Hardware Version:
Firmware Version: 1.9.1

Just noticed after hours of troubleshooting the intrusion prevention system is considering my connection to my printer as a risk and is blocking it. 
 

see picture attached (in Portuguese, sorry)

 

is there anything I can do besides turn it off completely?

Need help with the Deco app, setup, Ethernet backhaul, network switch or rolling back firmware? Router or AP mode? https://community.tp-link.com/us/home/forum/topic/699816?page=1

Hi, could you please refer to this link to help me submit the Deco APP log:

How to submit Deco APP log

 

Can I have the model number of the printer? Are you using any printer-finding/network scanning software, such as SANE?

Wait for your reply.

Best regards.

Hello David,

 

thank you for reaching out!

 

I've followed the steps and sent the logs.

 

The printer is an Epson L355.

 

regarding software, when using a MacBook I've only used the option directly in the system settings to add printers. When using iPhones we have to use the Epson app Epson iPrint. For Windows machines also just the windows printer setup or downloading driver from Epson website directly.

 

I have noticed the Epson was not appearing on my device list when this security was turned on, when I turn it off it appears and I'm able to send requests to the printer again.

 

Note: this was not an issue before, has this printer for years and all worked fine. Not sure when it started but might some update that made the system believe the printer is not safe anymore.

Hi @David-TP, 

 

I've noticed the exact same behavior with an Epson L555 but instead of a Deco I'm using an Archer AX6000. The Intrusion Prevention System is also blocking connection with the printer.

  @Angel5215 Hi, can I have a screenshot of the attacking records, such as:

Did you use any official or third-party software to manage the Epson L555 printer?

Wait for your reply.

Best regards.

Hi  @David-TP, 

 

Sorry for the delayed response. 

 

 

I'm using the official driver from Epson webpage, and just the default setup from macOS 26. Printing works again when disabling the Intrusion Prevention System from the Tether app. Just wondering if a future update might toggle the settings for this as printing worked with no problems before. If it also helps, the AX6000 V1.0 is running the firmware 1.4.3 Build 20250725 rel. 18118.
