Send me a message that will get printed on my home receipt printer. No, I’m not kidding.
While I have implemented detections on both the server request side (timeouts, sane defaults) and the client side (hard limits on print frequency), it is possible for a motivated attacker to bypass those. In that case, the worst thing that can happen is that there will be a stack of paper at my desk in the morning, a scowl on my face, and a swift disappearance of this fun project from my website. Don’t be a jerk.
