According to the documentation the paper size chosen by locale.

When using UIPrintInfoOutputGeneral either US Letter size or A4 is picked, depending on user locale.

Do you know how can I change US Letter to A4? Need to change user locale settings? – János Oct 14 '16 at 13:39
Yes you need to change the locale – Thomm Oct 14 '16 at 14:55
I have (1) Hungarian (2) English (U.K.) set as language – János Oct 14 '16 at 14:56
It regards the system locale, are you testing on the simulator? – Thomm Oct 14 '16 at 15:07
Nope, on device with real printer. – János Oct 14 '16 at 15:08
You need to check the locale within the settings of your device. Or you can try [this](http://stackoverflow.com/a/5014295/4019540) to force it – Thomm Oct 14 '16 at 15:09
Checked: (1) Hungarian (2) English (U.K.) **NOT** English US – János Oct 14 '16 at 15:09
You could try [this](http://stackoverflow.com/a/5014295/4019540) to force it. But in any case, there is a different issue at hand, one regarding your locale as the documentation clearly states papersize is determined by locale. – Thomm Oct 14 '16 at 15:12
