The air intake and exhaust openings of a printer console are acoustically designed to muffle sound from within the console from escaping. As seen in Fig. 1, a printer console 10 comprises a wall 11 with an air intake port 12. An air exhaust port 13 is located in wall 14 which has connection with the interior of the printer console where the print mechanism is housed. As seen in Fig. 2, intake port 12 connects to an intake chamber 15 which houses blower 16. Walls 17, 18 and 19 of chamber 15 are lined with acoustical material, such as polyurethane. Interior panel 20 of acoustical material forms a muffler for intake air with walls 17, 18 and 19 and provides an air passage which offers low impedance to air flow while attenuating noise from inside console 10.
