Paper Sizes on Android 5.0 On the Android print screen, I only see American paper sizes (Letter, Legal etc.). Is there a way to add or switch to ISO sizes (A4, A5 etc.)?
The issue is linked to the language you've set in your Android device.

Most probably you set the language as "English (United-States)" and with these settings you only get the American format in you "Paper Size" dropdown.

Therefore, if you want to have the ISO size but still keep your phone in English, you just have to set the language of it in "English (United Kingdom)" and your problem will be solved.

Manipulation :

Settings > Language &amp; input > Language > English (United Kingdom)

Close your apps and try again, in "Paper Size" you should now see the ISO formats.
