I just purchased a used HP Envy 5530 inkjet printer. I have no reason to think that it is compromised by malware, but at the same time I don't want to chance plugging it into my network or computer just to save a few bucks over a new printer.
My plan (and understand that I have no experience with security so this may all be stupid) is to download the latest firmware for the printer and try to install it directly from an SD card. If that isn't possible, I have access to an old netbook running windows XP that I may be able to use.
My question is whether you think that installing a new firmware would eliminate any potential malware that might be on the printer?
Any other considerations?
