I suppose that pictures speak louder than words, so here's the problem:
As you can imagine, the vertical lines at the bottom and right are not intentional. In the preview before printing the image fills the paper vertically, and this exact image with those exact settings printed correctly after a reboot. (The white margins are correct, btw.)
Weirdly, the photo isn't cut off at the bottom. It's actually compressed vertically, so that it's the full frame above the random lines but the wrong aspect ratio.
I'm using Photoshop CC (latest update), Print Studio Pro 2.2.3 (latest) on Windows 10 (latest updates). The firmware on both printers is current.
I should note that it happened before the most recent PS update and Windows updates. (It's been on and off for about 6 months.)
This occurs on both my PRO-100 and PRO-10, but only after printing a handful (it varies, but as many as 20) of photos perfectly. Sometimes closing PS and re-opening it cures the issue, other times it requires a reboot. But the problem always crops up again.
Paper size, image size, color vs. BW, color profile, nor just about any other setting seems to be related. It happens regardless.
Other than being an annoyance, this is wasting a lot of paper and dye/pigment.
Does anyone have any ideas??
Thanks in advance,
