useful when you need identical sections with different settings.
The consequences of empty back sides for printing and page numbering
In a Duplex job, the last page of a section may be empty since each new section starts on a
new sheet. You may wonder what this means for the number of 'print clicks' and for the page
numbering.
Note that an empty page is defined as a page that has no content and no Master Page. To
suppress the Master Page on otherwise empty back sides, check the option Omit Master Page
Back in case of an empty back page for last and single sheets, in the Sheet Configuration
dialog. (See "Sheet Configuration dialog" on page1004.)
As of version 2020.2, a page that only has a DataMapper PDF background is no longer seen
as empty. This may affect the output of templates created with previous versions.
Print clicks
If a page is empty, but still sent to a printer, it may be counted as a 'click' on the printer.
To avoid this, you could check the Omit empty back side for Last or Single sheet option in
the Duplex printing settings. This resets a page to Simplex if it has an empty back side. The
resulting print job can then be "mixed plex"; in that contains both simplex and duplex pages.
The omitted back side isn't sent to the printer, so it doesn't count as a print click.
If a page is empty, but not omitted (the Omit empty back side option is not checked) it will still be
sent to the printer and may count as a print click.
Page numbers
An empty back side that is omitted from the output does not count in the page numbers either.
If a back side is empty, but not omitted (the Omit empty back side for Last or Single sheet option
is not checked) it will be skipped from the page count unless the page numbers continue on the
next section (see "Configuring page numbers" on page481).
