Another printing problem

[Rolf8103]

Whatever I am doing, I do not get as hardcopy what I am seeing on the screen in the preview mode. Nothing like scaling and the like helps. When the printer has finished its work, the "format" on the screen has changed, i.e. becoming smaller or bigger. No such problems with FM5.

The other day, we had an update on the virus scanning software and I have updated Adobe reader from version 5 to 6 but no other changes have been made to any software or any driver. Could the virus scan software cause such problems??
