WPS button for WPS printer

I've been trying for a while to make a printer work with my OpenWRT router, it's a Epson L3150 and it works only with WPS. Currently that button resets the router. Is there a way to make it so pressing that button enables WPS temporarily? Most of the threads i saw on the subject were really old or presented conflicting instructions.

Any help is appreciated.

Ap without physical wps button on (connecting printer) - #10 by hnyman might still work.

that didn't seem to work so well, says the file is missing, even with the full wpad installed

Never tried, but you make a screenshot when file is missing....
