Elements 2018: Can no longer print on my EPSON ET-2750 printer

Are you using the image format of Photoshop or are you using a standard jpg format?

It isn't your fault. The printer is not designed to work with adobe products.
It will work with a standard jpeg format and it works fine if you use a different program like a word processor program. Personally I think it is some of the worst software for a printer I have ever encountered. I have been around graphic arts and computers since about 1969.
I am still using mine. But I am using it for word processing using libre office which is a free program on the internet. Most of the time it works. Occasionally it malfunctions on art work.
When I get into difficulties with it I switch over to a Brother Laser Printer. Not everyone has that choice. The ink is cheap on the Epson line. I also keep that microscopic printer screen close to the computer.
Why someone puts a 1.5 inch screen on a critical part of the machine is beyond me.
When something does go wrong it has to be fixed on that little screen if it is fixable at all.
Jpg format will print 4x6 prints but you have to use a program other than Adobe after you fix it with Photoshop or photoshop elements 19.
I have not tried it in GIMP on a linux computer yet.
GIMP would probably work.
I have several older computers with Ubuntu as an alternative on them. I do not like 10 much because it took away the bios and put it in the program.
Thus Ubuntu is just starting to put together decent operating systems that work within the windows 10 frame work. Personally, I think that is antitrust material.
The key to the machine itself is a compatibility issue Epson has had from the start.
Shame, the printer might have taken over the inkjet market otherwise.
