2021.2

Note
Use a print format that supports Duplex/Simplex switching to get a proper
Mixplex job. PDF is not suitable as it has no device control.
Print sections always start on a front page. To avoid empty pages between
sections, consider combining them into one section, and use page breaks to
push content to the next page (see "Page breaks" on page504).
l Check Tumble to duplex pages as in a calendar.
l Check Facing pages to have the side margins switched alternately, so that after
printing and binding the pages, they look like in a magazine or book. See "Pages"
on the facing page to find out how to set a left and right margin on a page.
Note
Master Pages, Media and Duplex printing options can also be set in a Control Script (see
"Control Scripts" on page913 and "Control Script API" on page1405). This is especially
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1025.)
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
