Back in the late 90s there was a common scam run against big-ish offices.
A caller would call asking to talk to the person in charge of printers, typically either IT or Facilities.
Once connected they would say that they are sending out the recipients free gift, which was some lame piece of electronics - often a small television. They would get the work address and confirmation to ship the free gift. They would claim that along with the free gift - they would send a sample toner cartridge that had "super fine toner in it, certified by HP to last 3 times as long as other toner cartridges"
Then, along with the free gift, a PALLET of toner cartridges would be sent - along with an invoice for some ridiculous amount.
When I got my first call about these "super fine toner cartridges" - I got suspicious and contacted HP. They told me about the scam - but that it was hard to find the people. They asked me to get as much info as I could from them if they called again. I got a call again, got as much info as I could without accepting the offer for the free gift - but they wound up sending it to me, along with the pallet of cartridges as well.
HP came to my office and picked it all up after contacting them again.
Over the years - I received more of these calls - and as soon as they brought up toner and free gifts, I tol them I knew the scam they were running - and they would promptly hang up on me...
You can try not paying the invoice and see what happens.
Sounds pretty stupid.
I believe this was originally in response to shoe manufacturers mailing people shoes and then invoicing for them if they weren't sent back.
As for whether it applies to non-USPS shipments, I have strong doubts. The law says "mail", and my understanding is that because the USPS is a protected monopoly, non-USPS carriers are explicitly not mail services.
They threaten, talk to A/P directly and demand payment (skipping over the original agent), all sorts of ways.
Then they call back again and ask for the person in charge of ordering toner and reference the exact model. Sigh. Almost as bad as the "yellow page" people.
I'll refer you to the CAN-SPAM Act of 2003, which does not just govern unsolicited e-mail, but all commercial mail which the law defines as electronic communication (bulk faxes, etc.)
The printers are on public wire.
You had not done any crime by using Google to find them.
You obtained access to their open HP admin panel via public link with no password or credentials you had to pass.
You haven't stole any information and, furthermore, there is NO confidential information even to be stolen to start with.
On the top of that, you cannot even determine who they are (name, company, address, email, nothing?). They are totally undefinable sitting by a raw IP address. Sure you know someone is using HP printer. Can you get legally punished for that?
I don't think that taking advantage of a publicly accessible information is punishable by jail, especially since noone got hurt and no information were stolen, whether it is information someone made their living off of (Aaron case), or just totally worthless information as of what brand computer of printer is being used. It would be hard for a company to sue you -- (lack of merit)?
If Google got away with snooping private data from open Wifs (and I am sure they made some sort of use from all that gathered data, even if only internally), then I am pretty sure you wont get any heat for such a petite stretch of snooping people's printers.
another though: you may say that someone can sue you for printing a page using their material and toner, but thats too little of damage to even start with. However, arguendo, if you would get slammed with class action lawsuit, you are most likely a millionaire from your idea anyways :)
I can see them getting you for spam, just as they can with unsolicited faxes I believe, but anything more than that? Seems a little silly.
To add to the printer/fax comparison, I have known people who used printers in different physical locations within an organization as a "fax machine" that was easier to use with a computer. Need to send some documents to the guys across the state? Print it to them.
There have been case(s) I think (in USA) concerning websites where it was argued successfully that placing an non-password protected page available on the public internet was implied consent to access/use that service.
That seems the right way to do it. You can't then, for example, put up a website which enables printing and then claim that people who use it are financially liable for using that service.
That would be like putting a bench on a busy street and then popping up and charging people if they happened to sit on it - if they sit down, you can tell them they're not authorised to sit without payment, or you can advertise lack of authorisation (eg with a price list) but otherwise you're implying consent.
Now not every layman knows how to properly hook things up to the internet, but there is a definite implied consent in doing so. If the pages were restricted by password and we were bypassing it, or they were locked to an IP and we could spoof it, then there wouldn't be an implied consent to access the service being provided; but that's not the case here.
If you want to look at intent then it's notable that many listed are University addresses - people setting up those printers absolutely know what they're doing.
If you purposefully used excessive paper/ink or you kill the hardware with a broken firmware update then those things are definitely not authorised by the implied consent and would constitute vandalism.
(also, how very considerate of you)
The Federal Prosecutor threatening with 50years of jail time Or you can accept this no-brainer plea bargain for only 1year.
See also, 50 million posts on this subject last couple weeks since prominent software engineer suicided himself.
There's even less barrier to sending a junk fax, and that can get you fined and potentially jailed.
1. write a script to scrap google links to HP admin panel
2. filter out the IPs that are from US (given you want to work on US market)
3. assemble the list of printer types and current toner levels.
4. write a script that will print to each of those printers a one single page, stating your company "Cheapo Suppliers Inc" was notified that "your printer is low on toner. Call xxxxxx to re-fill. Lowest prices quaranteed within one day delivery!". You can add link to your shop page that already redirects user to specific type of printer they have, some type of one-click order (based on which toners are low).
5. daily rinse repeat.
6. sell your business to HP (at least try to).
