How delete 1/8 inch white border around 13X19 print on Epson ET-15000?

Most Epson printers I’ve used have had borderless printing as a standard feature, but it isn’t always obvious how to set it up. However, I decided to look at the specs for this one, and there is an interesting line in the ET-15000 spec sheet that I was not expecting to see:

Borderless Printing Up to 11" x 17"

I am used to Epson printers being capable of borderless up to the maximum sheet size listed in its paper sizes. On the ET-15000, the largest sheet size is 13" x 19", and the original post here says “I want to fully print it on 13X19 Epson paper edge to edge” which I would normally think is reasonable to expect. But that line in the spec sheet says you’ll only get borderless up to 11" x 17"; if that’s true then borderless 13" x 19" isn’t possible no matter what software you’re using (although a software RIP might get around it).

There’s nothing Photoshop or any other photo editor can do to achieve borderless 13" x 19" if the printer itself can’t do it.

One reason I asked what paper size is specified is that on the Epson printers I’ve used, to get borderless you have to choose a paper size with “borderless” in the name, as shown below. (My printer is 17" wide, so I picked a full width paper.) I am not sure if it works exactly the same way for the ET-15000, but if you see “borderless” sizes for 11 x 17 but not for 13 x 19, then that would be even more evidence that the ET-15000 can’t do borderless at 13 x 19 inches.

From page 84/85 of the manual for your printer :

'A3+ (13 × 19 inches [329 × 483 mm]) size paper is not supported for borderless printing'

Can that printer actually print borderless? Shouldn't you consider starting there? Maybe the info is in.... the manual???
