If 3rd party ink can give you a computer virus then the printer isn't built correctly. There's no reason that should happen.

If you’re using an HP printer, such an attack is feasible because of the chips that they use for detecting ink levels, verifying the manufacturer, etc.. As a result, any cartridge could potentially infect your printer (since potentially an attacker could modify a first party ink/toner cartridge and replace its chip with one infected with malware). As such, the only fully “safe” approach is to modify your HP printer such that it doesn’t connect to these chips at all.

I look forward to HP providing firmware that will prevent the printer from communicating with any ink/toner chips (and that will allow printing to continue unabated, relying on the user to notice that ink levels are low and that new ink is required).

If you get 2 years out of an HP product, you're doing pretty well.

Yup. Just like toll roads, I'll go out of my way and spend extra effort to avoid printers on principle.

Really makes me appreciate the free printing services at my local public library.

a company that values their customers as human beings.

Good luck with that

Malware. They’re saying that malware imbedded on the cartridge can hop to the printer then onto networks.

Which is why you shouldn’t buy from unknown vendors. But even certified cartridges can be tampered with if you’re getting it from a sketchy source.

I used to work for a laptop repair company. Nothing made me hate HP than having to work on their machines. Dell? Lenovo? Hell, Asus? I’d take ‘em all over an HP any day.

I have a HP laptop. I hate its UEFI.

1. Drive lock:
   This utilizes the ATA security commands. DriveLock uses master and user password. I don't know how exactly they are used, but simply the user password is used for unlocking the drive while master password is required to reset it.
   While enabling DriveLock, HP UEFI ask me for a password. Which one is it? Does it re-use it for both? Does it use the admin password as master? Does it generate and save the master password in UEFI? I should probably test it out with hdparm.

2. Vanishing boot entries:
   Did you just boot up from external drive? Where's the boot entries? ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯ Can you at least add them in UEFI settings like with any normal computer? Nope. You need to use either efibootmgr or bootice. I usually just boot Hiren's Boot (PE) and use Bootice. Is that it though? Nope. The boot priority won't be saved. You need to head back into UEFI settings (and don't you dare forget to unlock your drive, or else start all over), go into boot settings, "OS Boot Manager" and then put them in correct order. What they don't tell you is that if you get out to "Save and exit", this won't be saved. You have to press one of the F keys, I believe F10, to save the boot order, and just then you can "Save and exit".
