On latest OS-X when printing to an Epson 3880 from Lightroom CC 6 using "Printer.." and then selecting print in the dialog everything works great and I get a perfect A4 print.
When just using the Print button I only get parts of the print on a 4x6 inch area on an A4 paper. This is both when using my user template for A4 printing and when using the Lightroom template "Max Size" also on A4.
I did try resetting the Epson 3880 driver.
This is not a serious issue since I have a workaround, but a bit surprising. Anybody know what could be wrong?
