Hey thanks a million the two of you - really appreciate the responses above - I got sorted!! Photos on the way back from printers now, how exciting

Doing some quick checking suggests that Dry Creek Photo may have profiles to fit your needs [edit: or can create them]. https://www.drycreekphoto.com/icc/ (scroll to the bottom of the comments on this link to see the reference: https://www.dpreview.com/forums/thread/1004800 )
Note (as this threw me at first) the list of profiles on Dry Creek only shows up when you pick a region that has a provider that offers the combo you need. I've not found a specific way to search (though it was a brief skim) so you may have to exhaustively search the regions for someone using that printer and that paper.

What profiles, for that paper and machine? Then I would ask the print service after those, since if they use those specific printer and paper type they also should have the right profiles for those.
Further you can search after the Fuji paper and see what is told about specs and profiling (calibration data) for that.
Fujifilm photographic paper FujiFilm Crystal Archive paper Fujicolor Crystal Archive Paper Digital Paper Type DPII Fujifilm icc profiles etc.

Hi Ian
 
Just done a little investigation into the macro and I think I have found a way to get the text and size working for you.
If you create the macro but without the resize of the document.
When you go to the batch job window select the format you want the images in, then in the width and height boxes put your 2400 x 1800 uncheck the A (aspect ratio) and it should output the macro with the text and the size you need.
Just checked and at this point in time the macros cannot rename the image Ian.
I hope this helps with the Macros Ian.
