Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Nothing about those ink cartridges is special enough to justify the kind of locking you're justifying here, nor is a printer a service relying on HP operations to run in the same way an internet service or gas service is. And that's all assuming this was a rented printer, not an owned one.
