Not sure if this is right area, because its network, security, and printer issue...
I recently put a TP-Link Omada system in at my house:
Router: ER7206
Two Switches: TL-SG2210MP & TL-SG2008
Controller: OC200
Access Points: 2x EAP225 and 2X EAP615-Wall
One of the cool things about the Omada controller, is the dashboard which gives tons of information about your LAN, including data usage by each device.
My printer’s data use has caught my eye. The printer is an HP1525NW color laser. Over a 19-day period, it used 95TB of data. Upload and download each. So total almost 190TB. And that’s not a typo, terabytes.
This printer, on a busy month prints maybe 10-20 pages of documents. Rarely any photos, and nothing even close to this amount of data.
I did a factory reset and made sure the firmware is up to date. Incidentally, the newest firmware version from HP is 2014.
It continued to upload and download a large amount of data. In a 24 hour period 17.35GB. I hadn't printed anything other than a test page during that 24 hours.
I created an access control list setting that blocks the printer from the router (so it can't talk to the internet), but still allows it to talk to the LAN, so we can still print.
There’s no shortage of online articles that say printers are a vector for network intrusion. Many specifically mention HP.
I’m wondering if I’ve fallen victim to that? Have a got a little nasty creeping around in my printer, and LAN? Or is there something else going on that I’m not taking into account.
Just wondering if anyone else had similar experiences, and what, if anything was done to mitigate it?
