Lost my letter size printing?

[Raydean]

My "Letter size" print job to my printer and/or to Adobe PDF print has changed and the pages on all of my different layouts are no longer sized properly. I have to reduce my "page setup" in Filemaker to 94% to print any one of my layouts. That reduction fowls up the data/ print to some degree and I need to get back to the original letter size. The Mac finder preferences are set to "letter size".

I have no idea how to check to see if this a Mac issue or if it is my Filemaker 8 layouts?

The only change that I am aware of is I did download Apple's newer firmware update a week before this problem occurred. Nothing else has changed in years.

Any Ideas???
