Upside-down pages for double-sided printing are problematic

[derde]

None of my printers seem to position the text on the page with great accuracy. When I print A5 content on A4 paper, the printer does not print the inverted page with the expected margins - specifically the A5 top and bottom margins, which print as the left/right margin on the A4 output, but as the right/left margins when the page is inverted.

I'm searching for an option to suppress the flipping of the page, but not finding it.

You're looking for the --short-edge setting.

I was going to say it doesn't do that .. because I've tried ... but when I tried it for two a5's onto a4, it does work. Thanks!
