For some reason now, whenever I print any document from WordX - whether that document has been prepared from scratch by me, printed from an archive or template, or it was created by a third party, I always get an error message to the effect that Parts of page 1 are outside the margin.

This might make sense for third party documents, but not for those I have created myself from a standard document set-up or pro-forma.

And why only ever page 1?

The actual printing remains unaffected and nothing is "missed off".

What is causing this, should I be worried about it becoming a real rather then spurious warning and how can i stop it?

I print wirelessly from WordX on an i7 quad-core iMac under MacOSX.6.8 via a NetGear DG834G router onto a G4 eMac under macOSX.4.11 and thence via USB to the DeskJet 840C - a system I have had for over 18 months and which, until recently, gave no error messages.

Thanks.
