Crashes trying to print selected cells

[Chirs]

EU REPORTING THAT WHEN SHE TRIES TO PRINT A BLOCK OF
CELLS FROM EXCEL IT SOMETIMES CRASHES EXCEL. THE SAME
CELLS DO NOT ALWAYS CRASH EXCEL. THE MESSAGE IS: WINDOWS
HAS ENCOUNTERED AN ERROR AND MUST CLOSE EXCEL. THIS
HAPPENS SEVERAL TIMES A DAY.

Where do I start? I used the Detect & Repai function but
it did not work.

Thanks
