Yes.
If you have blank columns set to a width of 3 or 23, they will be reset to
default which is 8.43.
Other columns with data or formulas will autofit to size.
I prefer to run John Walkenbach's ListFormulas macro to list formulas, cell
addresses and results on another sheet.

Then you don't muck about with formatting of the original sheet just to see or
print the formulas.
