I have heard a figure of 40A inrush mentioned, Like herehttp://www.crs-uk.biz/pdf/HP_1100.pdf
Doesn't say how many mS, but MCBs are fast acting.

Lots of appliances have inrush current figures of 40A and higher. It
means nothing.

If the printer is popping a trip then the pr is almost certainly
faulty.

Might be the last straw that breaks the camels back..Although things are
better today, the inrush on a roomful of PC and monitior SMPS's was
enough to flip a 30A MCB in my day.

Had to be switched on one at a time..
