I have heard a figure of 40A inrush mentioned, Like here

Doesn't say how many mS, but MCBs are fast acting.

Fast acting yes, but you would need 160A to push a type B 32A MCB into
its instantaneous trip response. (or 100A for a 20A MCB on a radial)

(note also that laser printer don't usually blow their plug fuses)
