How to Capture Outbound Packets from my HP Printer

asked 2020-09-15 00:41:35 +0000

I have a HP M577 Printer, Connected to my Home Network with a Static ip Address and I have a Huawei NBN Modem/Router, and I am keen to see what traffic is going in and Out of my Printer, especially if its sending data to the Internet. I dont need to capture From My PC to the Printer, mainly I am Keen to understand what is communicating to my printer.

From what I have read, it seems that maybe this i not possible because I would need to install a Driver of some sort, is this true, or is there another way of capturing Packets from my Printer onto my Windows 10 Desktop PC.

An advise would be really appreciated. Regards Steve.M

Can you describe to the plumbing/topology of your network? (Wireless, wired, mix)

Wireless capture with Windows is tough.
If possible, add a switch between the printer and router, then mirror to a port for the PC.
Here are two videos that show how to do this with a small switch:
Turning a NetGear GS105E into a network monitoring device
UNIFI FLEX MINI SWITCH (mirror port)

Capture using a monitor mode of the switch

I have both the Printer and Pc Hardwired, I have a Huaewei 4 Port NBN Wireless Router & Dlink DIR-882, 4 Port Wireless Router, and I can Have the Printer Connected to Either Or. at the Moment the Printer is on the Huaewai, while my PC is Connected to the Dlink.

Have a look at the Wireshark Wiki page about capturing on Ethernet networks.

On a low budget, I like to use a NetGear GS108Tv2 (I have not tried the new v3 yet, but it is probably a good choice too). You can configure a mirror session on it and then put it in between the printer and the router.

The GS105E works as well, note that Netgear has two very similar models in both the 5 port and 8 port range and you want the Smart Managed Plus "E" versions to do port mirroring.

It appears that the GS10x series are end of life and are being replaced by the GS30x series.
