Direct Instax printing is only supported for the older Instax Share printers (which are discontinued) and not the newer Instax Link printers for almost all Fuji cameras. I was very disappointed to find my X-S20 doesn't connect to my Instax Link printer.
Nice list of hacks. I’d like to see a more in-depth demonstration of the XApp film simulation switch you mentioned in your video if you’re looking for suggestions for future videos.
