So it sounds like one of those bad jokes right (he he is your printer running, you better go catch it!! lulz) But on a serious note Iv never once heard of anyone talking about how to lock down a printer, and if I was going to go do something malicious to a company it might be a real target of mine think about it...
- It prints possibly confidential documents to be signed.
- It scans documents and in some cases shoots the users emails, if that email account was breached something like one of those phishing attacks that shoots you a sketchy zip files with a simple password, then asks you to open it with excel and macros enabled could be really devastating to a user or even potential customer depending on who you work for.
- Hippa compliance breach
This all sounds really bad and given a lot of printers seem to run some kind of lightweight...
