Same issue using 7plus with IOS 11.2.6.
After googling possible solutions, I’ve gone to settings and set the font to the smallest possible setting. This changed nothing. I believe (w/o going back) that someone asked what the person was attempting to print...I just noticed it does appear to be photos I saved of docs as I just tested an email and it printed in smaller font. I am unable to change font from my phone on the print screen prior to each print as far as I know. Thanks for any
help. The pasted example cut off a ton of info and font is huge!
iPhone 6, iOS 8.1
