This from a user:
Why am I getting a blank page after each page of my financial statement?

Response from Softrak:

This could be due to having 'blank' or spare columns at the far right of your FS - in addition, there could be many blank rows at the bottom of your FS.

If you remove these extra columns/rows, the problem should go away.

Or hide the extra row(s)/column(s) to suppress printing.

Or, check the margin settings under the File / Page Setup.
