Prints intermittently not centering with Epson SC-P800
I'm experiencing a frustrating and expensive paper and ink-wasting issue when printing 13x19 size prints from Mac OSX 10.13.4 and LR Classic CC v8.0 on my Epson SC-P800. Things are printing well for awhile and then if I have a paper jam, say, or have to cancel a job because I started printing the wrong photo, when I try to print again with the same exact settings (page size, print size), the prints come out with the left margin suddenly a lot wider and the right side having no margin (borderless).
I have tried to troubleshoot this problem with Epson and they believe it is something with LR software and/or OSX because I'm able to print fine from Preview using a jpeg created in LR's print to file feature and the same Epson printer driver settings.
The major reason this is so infuriating is because of its intermittent nature. I seem to always be able to print small page sizes fine (4x6s, letter) in LR, but it's the bigger sheets where I run into this problem. I've finally learned that once this problem starts, even if I can subsequently print smaller prints fine, there is no way to predict if I'll be able to print the bigger sheet sizes with correct centering. Sometimes miraculously the problem goes away--rarely--but usually I'll have wasted another half sheet of 13x19 exhibition fiber paper before i discover the uncentered printing problem.
Anyway, the only temporary solution I've found is to do a major Epson printer software purge:
- Restart Epson SC-P800
- Delete Epson folder in Library/Caches
- Reset printing system in System Preferences
- Reinstall Epson SC-P800 driver software
This 15-minute solution definitely works, but is obviously a major pain.
So this discussion is mostly a rant and a plea for Adobe software engineers to get to the bottom of this. For what it's worth, the problem seems to occur more often when I use Printer Manages Color, 16b output, and the Epson ABW (advanced black and white) settings, though I have not paid attention consistently.
For now, for 13x19 or bigger sheet size prints, I will use LR's print to file feature and then print the job with Preview--a slowdown in my workflow, but very reliable.

Addendum
Now even Preview does not print correctly: similar issues with the LR print to file jpegs not printing centered, or with different sizes (8.5x11 on a 13x19 sheet, for example). Just f@#^ing infuriating.
