Printing A3+ Epson XP-15000 LRC

[roberth78002683]

I Am having trouble printing in the A3+ format (13x19) on an Epson XP-15000 printer from the Lightroom Classic print module. The printer is set to A3+, but A3 is the largest choice in LR setup, and the sliders are limited to A3 dimensions, resulting in a truncated print.  Any ideas?  Thanks.

Start from scratch and make a new, virgin Print Template using all the settings including the Print Driver. Any better?
