double-side printing: blank pages are not counted as even? Mac OS X: 10.14.6
Preview: 10.1 (944.6.16.1)
Printer: Canon 2900


I followed this to print double-side: How to control manual double-side printing on Mac OS X Lion?

The problem: when choosing "Even only", the blank pages are not printed. Given an example: I have a pdf file with 10 pages: page 6 and 8 are blank


Odd only: will print 1, 3, 5, 7, 9
Even only (reverse order): only print 10, 4, 2


so the result is:


1 |
3 |
5 | 2
7 | 4
9 | 10


What is the reason? How can I make the blank pages are printed as normal (even) pages?
Preview should normally print blank pages in a PDF document. They are still valid page objects. There is no setting in Preview itself to skip blank pages.

It's most likely that your printer has its own setting to eliminate blank pages. You'll need to check its configuration to see if such a thing exists and is on.
