It is! I copied it from the screen of my test machine to my main machine
and from habit automatically put a "/" after the ":". Well-spotted.

That is exactly what should happen.

Now would you repeat the lpadmin and cupsfilters commands but use the
PPD for your printer. (That's the only change to make). How does it go?

To actually print to the printer you will have to have -v as

 usb://EPSON/WF-2530%20Series?serial=514B34593134343081&interface=1"

I got that from your error_log. You can check it with 'lpinfo -v'.

Can you print?

Cheers,

Brian.
