Every now and then, I use the "Layout" option in macOS's print dialog to fit two pages on a sheet, for instance when printing presentation slides. For some reason, this sometimes leads to 4 pages being printed per sheet, rendering the slides hardly readable. Happened twice to me today.
Does anyone know why this is happening and how to prevent it?
Update
In response to Tetsujin's comment:
- I'm running the latest macOS Sierra 10.12.4 (16E195) but I've been experiencing this issue with previous versions of macOS (formerly OS X) as well so I don't think it matters.
- I print from Preview and Safari and the problem occurs in both cases.
- I usually print two A5s onto one A4. I'm fairly certain, there's no spilling over.
- The print dialog shows the correct number of pages.
- "Is this happening at the app or at the printer?" – Not sure what is meant.

I have the same problem. The only way I manage to print 2 pages is printing it as a two-page layout PDF (which generates the expected two-pages per sheet layout), and then printing this as a one page per sheet. If I print directly, it will print 4 pages per sheet when I specify 2. This happens for the last 3 Mac OS versions, independent of the printer or program (I just checked with a PDF from Safari).
This happens from Sierra up to Movaje (as of now).
