Cannot set margins to zero any more. It used to work fine. But I upgraded to Neon 5.8.5 and suddenly found that the smallest margin was now 4.23mm. Most (pretty much all) PDF's have margins already set. So to print at the size originally intended it MUST be possible to set print margins to zero. But now the margins are a minimum of 4.23mm greater than they need to be, when one attempts to print. Of course, this latest bug renders Okular completely useless when to comes to printing labels.

The printing dialog is QPrintDialog from Qt libraries. Please report this issue directly to Qt developers via https://bugreports.qt.io/
Seems a bug was reported ages ago regarding missing functions on QT print dialog. However, setting a page to print full page is possible already, apparently... "This is already possible using the QPrinter::setFullPage(bool) function."

Would you mind sharing the link to the qt bugreport?

This isn't an issue with Okular or the Qt print dialog; the allowable minimum margins are determined further down the printing stack, by CUPS or LPR another part of the printing system. My printer + CUPS +LPR combination allows 0" margins on all sides, for example. You might try reporting against CUPS or LPR.
