I use a iMac with El Captain, LR6 and a Epson Pro 3880. I want to print size A3 and A2, but Lightroom always do only print in DIN A4 on the big paper! I have changes settings in any way, no chance! I used the presets from LR, look at tutorials, changes layout at LR, checked the printer preferences.
Same with my MacBook Pro!
If I use Apple photo, I can print in any size I want.
I do not understand where my fault is.
Can you help?
In the print module have you the Page Setup at the bottom on the left hand side, set up for the correct printer? This uses the properties of the printer you wish to use, so there will be A2 and A3 options to choose if the printer is capable of those sizes!
Yes I know this and I set the size paper for the printer. But it doesn't work.
Is your printer driver ip to date I have an A3+ size printer and don't appear to have the same problems! What happens when you attempt to print?
