Thank you!  I think I see something in your screenshots.  I was able to download that Keith Cooper test image and for me it prints as a black rectangle on my 8550.  I think it has something to do with the grayscale gamma 2.2 color space.

Looking into it now...

Here is the screenshot. It works fine to print from Affinity photo and Epson print layout so the printer driver seems to work.

If you get a picture on the preview but the printer doesn't print, that points to a likely driver problem because that Epson preview window is showing you what the driver received (and is about to print).  If what you see in the Epson print preview doesn't print, then your driver just lied to you: didn't print what it said it was about to print.

Can you post a screenshot of the main window showing the live view with the Printers and Settings tab open so I can see the printer settings?  That way I can replicate all your settings and try to print on my 8550.

Why 2025 would work and the 2026 version doesn't: I can't answer that.  The 2026 version will be sending slightly different (better) pixel data but I don't know why that would affect it.  I guess it's also possible that the 2026.100 bug corrupted some memory that isn't being used by 2025.105: to test that, reboot your machine and try the 2026 version again.  If you still have a problem, you can hold the Shift key, click the "Properties" button to open the printer driver, set up your media type, size, etc. in the driver, click OK, and try to print after doing that (in case some settings got corrupted).

I've been developing Qimage for 28 years and I see anti-virus interference on occasion, especially from poorly written AV programs (PrevX, BitDefender, and Norton come to mind!).  Windows Defender is not a problem so if that's all you have, it isn't that.

And yes, like I said, I did make something of your message: that usually appears when the plug-in is trying to access a file and can't for some reason, hence what I suggested.

You didn't mention it so I'll assume you didn't make the mistake I pointed out: installing under an administrator account and then switching to a different account to run Qimage.  The only other thing that I can suggest is uninstalling and reinstalling Lightroom, then reinstalling Qimage so it will renew the plug-in.

I do have a picture in the print preview window but it still feeds the paper straight through. When I uninstall the latest version and reinstall 2025 everything works fine.

Mike, I'm using Windows Defender and looking for a way to disable it.  I've been in the AV business for over 25 years and never had an AV product disrupt a program from running. Do you make anything out of the message that I attached? 

I tested 2026.101 extensively on the 8550 so I think you have an issue on your end.  Possibly corrupt printer settings or a printer/driver issue.  Have you tried printing with the print preview turned on in the driver to see if that preview also looks blank?

It still doesn't work.
