Abstract
A room has a door for closing a door opening in an openable manner. A thermal printer with electronic circuits is installed in the room. An air pressure managing system for the thermal printer includes a door state photo sensor for monitoring a state of the door, and outputs an open signal when the door is open. A dustproofing fan is actuated in response to outputting the open signal, for adjusting pressure of air in the thermal printer, to prevent the thermal printer from being influenced by air flowing from outside the door opening.
