algent I doublechecked you are right. I've been their a lot (epson) lately.
There's a mythical Ubuntu driver pacakge that will accommodate your Epson Stylus SX205----
https://www.ubuntubuzz.com/2011/10/download-various-epson-printers-driver.html
links are dead in that page. But this mythical driver pack for the SX205 is alluded to in this thread at an Arch site:
https://bbs.archlinux.org/viewtopic.php?id=98793
these are 10 year old posts though but all about the SX205. Can't find nothing recent. If they did exist for Linux and now they don't does that mean they just weren't maintained?
also vuescan has them for linux: https://www.hamrick.com/vuescan/epson_stylus_sx200.html
but I've never done business with them; I don't have an opinion.
openprinting claims to have a linux driver: https://www.openprinting.org/printer/Epson/Epson-Stylus_SX205
they claim in addition the the driver you have to install epson-escpr and gutenprint , cups etc. stuff you probably do have installed...
In 30 minutes of sleuthing I could find no patterns or consistencies which to me is odd...
ALso, can you find the name for this driver? YOu have that you might have a start. That's how I got my epson scanner running: it all started with the name. With the name I could double-check/cross-reference which models were accommodated by the particular driver. then finding the deb and rpm packs. After that it is more head-achey. Epson page changes EVERY time you do linux search....can be maddening. It wasn't easy but I'm glad I did it.
edit: after seeing the last post I am confused🙁
