Question about HP 178nw Colour Laser

36.3 cm is with the control unit. But with the paper drawer it's a good 40 cm and then the plug comes in at the back (6 cm for a normal one or 2 cm for an angled one)

38 cm with the control panel. But you still have to think about the power cable coming out the back. If you take a bent cable, that's an extra 2 cm. Best regards
