I am using LR 5.7.1 on Mavericks OS 10.9.5 and printing on Epson 3885 (similar to Epson 3880). A4 prints from LR comes out nicely. But when switching to print on A3 or super A3, the printing stops at the edge of the A4 paper and the portion of the picture beyond the right margin of the A4 size is not printed out. This problem does not happen with printing A3 pictures from Photoshop. Thus the issue is not with the printer or its driver. I have re-installed printer driver, and my LR and Photoshop. But the problem persists. Grateful to know if anyone else has encountered this issue. Thank you.
