wireless printer- a Trojan horse?

[Worried1]

I am new to wireless printing.

Stunned that the printer could connect with our password protected wi-fi - the laptops and phones needed password so why not the printer?

Shocked that my partner's desktop has a little pop-up asking them if they want to print on my printer. We do not have our computers networked.

I can't find anyway to ask an HP representative about security. Neither can I find anything on the website about security. My printer should not be muscling in onto my partner's computer, nor should it be able to access my password protected wi-fi.

Can anyone explain this?

I have posted on printers connected board but really I ought to be able to find out the answer from an HP representative, not from fellow travellers who may or may not have the expertise but may not say if they don't. 

HP is a big company, they should be able to afford people to do online typed chat to help, or receive email requests.

I am trying not to use my brand new printer that worked brilliantly until I find out if I am safe to do so.

Meanwhile I am hunting for a cable to join it by wire to the laptop, then I will be looking for howto disconnect it from the internet , and cancelling my membership to the instant ink package.

Printer which supports wifi direct does have a network itself. When it is ON, it will broadcast its network as a printer therefore computer(s) around can "see and talk" to it and if you wish to print, you need its password.

Note: It can't connect to internet this way, you need to conntect it to a normal network.

Hope this makes sense.

Thankyou for trying to help me.

You have not understood my problem. I do not want a printer that can help itself to my wi-fi without needing the password. That makes me feel unsafe. I thought that my wifi was password protected because everything else has to use the passowrd to log onto the wifi. Now I feel someone could hack into my wifi and other computers by piggy-backing onto the printer. 

Especially as the printer has managed to log a popup window or something onto my partner's laptop without asking permission. If it can introduce a message like that, then presumably it can carry other messages into computers.

Do you work for HP support? I'd really like to talk to someone who works for HP.

Thankyou
