I am searching for old Epson printer drivers to P600.
Anyone know where to download these files???
I don't know... no longer have Epson printers, BUT
... you might try Print Fab, it's a paid app for printing that provides support for special features, color control, etc, but also supports printers that are no longer supported by the original drivers, you don't even need the official drivers. Sometimes the problem with Epson is even the official drivers won't work with newer operative system versions.
I don't work for them, it's just an app that I have used many times with great results avoiding the issues of searching for the original drivers.
