Yes... they have changed something! At a guess the page size/margins on

their systems.

Check that windows update hasn't stuck a driver update in, or that some

are direct and some via a servers AD printer entry.

If not the above, try pulling the power to the printer (not turning it

off as that seldom clears settings these days) and then check that they

haven't buggered around with any settings (has an engineer out to do a

fuser replacement etc).
