One of the project managers is not able to print it out on 8.5 x 11 paper, but the document presets for InDesign are the same as before.
I suspect the project manager simply has his/her copy of Reader/Acrobat set to print at actual size, rather than "Fit" (assuming the InDesign page size is truly 8.5 x 11).
..the newly updated PDF is almost a .5 inch wider with the same export presets.
It would have nothing to do with export presets. How are you determining that half-inch difference?
...print to PDF is not an option...
It never is. From InDesign, Export is the only correct avenue to PDF.
Thank you for your answers, I checked in with the project manager and he is scaling to fit rather than full view. So, that solves it. Of course, it was a simple answer tied in with user assumptions.
The .5 inch difference was a bit of a scaling liberty that I took when measure. It was probably closer to a .25 inch.
Thank you for your quick response - made my work morning much easier!
