AU CONTRAIRE! I started having the scaling problem again this morning, in LR, so I tested printing out of Photoshop, too, just in case it was a LR/Printer/Driver "thing." And I "think" I have it figured out / solved. And JRSmit alluded to it, but I didn't tumble to what he meant. OK, this printer is "different" from other Epson printers. Several paper adjustments (platen gap, thickness) no longer appear in the driver - only in the printer's menu. When loading the paper in the printer it walks you through paper size, type, and provides sub menu opportunities for selecting platen gap, thickness, suction, and paper feed offset. AND THE TRICK IS (to prevent the weird image offset and scaling issue) THAT IN THE DRIVER, IN THE DROP DOWN FOR PAPER TYPE, THERE IS A SETTING AT THE TOP THAT SAYS "USE PRINTER SETTINGS." (UPS) After burning up a lot of paper and ink, (the manual is useless in this regard) I finally used the UPS option in the driver and the prints were properly printed via the LR print module. I'm still not getting a full "print preview" - just an image of the lower left corner of the image showing borders and where the image "starts" relative to those borders (I don't like that). But prints are coming out correctly laid out on the paper and the actual image size on the paper is spot on, w/o any printer induced scaling happening. I read through the printer user manual several times before even receiving the printer and saw nothing to indicate that this is apparently 'necessary' in order for the driver and printer not to get into a urinating contest. You still set paper size (even though that's redundant w/ printer settings) and orientation in the driver, along with resolution, high speed on/off, etc.
So, that's where I am at the moment. If there was justice in the world, Epson would replace the paper and ink I wasted due to what I consider to be really poor documentation / explication of "how this all works" when printing through LR / PS (and perhaps other applications). I'm still nervous, and will keep testing once my ink resupply arrives tomorrow.
And just for completeness, I'm printing out of LR / PS the latest versions from the cloud subscription, and I'm on a Windows 10, Puget Systems PC with plenty of capability.

ONGOING SAGA:All is not well in 7570 land. I have chased the weirdness down a bit - but it's still there.
First, I got up this morning and did a software check, and lo and behold there was another firmware update for the 7570. So, I installed it - naively hoping that it was "the cure." No joy.
OK, here's the ongoing issue. Parameters: printing out of LR on PC, latest version LR Classic from cloud subscription. Using Epson Legacy Baryta. One issue was/is that sometimes the Print Preview shows the "whole image laid out" (as is normal for all my printing from other printers - currently P 600 and P5000), and sometimes it only shows a corner of the image. None of the parameters in the Print Preview window have any effect on this. It is completely random. And this is not directly related to the real problem - so just a "notation" at this point perhaps indicating a buggy driver. The REAL problem was/is that sometimes the printer both "misplaces" the image by starting to print a good 2" farther into the sheet than it should based on how it's laid out in LR print module. AND, sometimes the resulting image is "compressed" on the long edge. In other words, if the image is supposed to be 12x18 on a 13x19" sheet, it comes out 12x17" but the "whole image" is there, just compressed on the long dimension. Nuts, right? But wait, there's more! Sometimes, with exactly the same parameters in printer/driver it will print offset but the right aspect ratio. Go figure. AND HERE'S THE REAL KICKER: It only does this on image files that are in portrait orientation. I even tried rotating the image in LR Library module and printing it landscape. No joy. I tried leaving it as a portrait orientation image in LR and printing in landscape mode w/ "rotate to fit" checked. No joy. I tried it on 17x22" paper... same issue, just larger and more expensive wasted paper and ink. On image files that are landscape in orientation, and printed "in landscape" orientation in LR, there's no issue. That's one of the reasons I was chasing my tail thinking, "It's fixed, no it's not, yes it is... " It took a while for it to dawn on me what was happening. I started keeping notes, and writing all the parameters on the edge of the prints.
And, if you've been following this saga, it also doesn't matter whether I use the new "USE PRINTER SETTINGS" in the driver, or use the actual media type in the driver that corresponds to what is set in the printer itself. In this case, Legacy Baryta.
Another data point. On page 100 in the user manual it shows the usual list of "paper config" items, color density, drying time, paper feed adj., paper suction, paper thickness, platen gap as "selectable" within the driver. BUT, in the driver when you select paper config, you only get a small pop-up window that only has the color density slider. So, for one thing, the manual and the driver are out of sync.
I have a call in to Epson Professional Tech Support. The first representative that I spoke with was having trouble with his computer and we had to abandon the session. They're going to call me back.
My preliminary thinking is that either "my sample" of the printer has some kind of electronic schizophrenia (and needs to be replaced), or the Windows driver (at least) and/or the printer firmware is wonky - at least as pertains to printing from the latest versions of LR Classic and Photoshop.
More later after I do have a session with Tech Support.
