When I print from my laser printer it causes my smoke detector to chirp but does my breaker not trip?

It's likely a voltage drop causing the detector to chirp. Your voltage is dropping momentarily under the load of the printer kicking on, and your detector is very sensitive to that. Your circuit breaker couldn't care less.

Thanks for the help. Would this cause any damage to the HT equipment I have?

Yes, but in most states a hardwired smoke detectors have do be on their own circuit.

That probably wasn't in effect when older buildings were built, and it may not apply to hardwired detectors with a battery backup.

Toner gets into the air. There was some medical studies on it, and I don't believe it was good for your lungs.
