Thanks to Ken Ray and Dave Cragg for pointing out the existence 'the
pageHeights'. I had missed this. Although somewhat eccentric, i.e.
Comments:
The value reported by the pageHeights property is a list of numbers
separated by returns. Each number is the height in pixels of a page
full of text.
You can use the pageHeights property to print the entire contents
of a field by printing the field, setting the field's scroll to the
first line of the pageHeights, printing the field again, setting
the scroll to the current scroll plus line 2 of the pageHeights,
and so on.
The computations used by the pageHeights property assume the
field's borderWidth property is set to zero and its margins is set
to 6.
it does look like the answer. Thanks to you both. There does at first
sight seem to be one problem, which is that if the last page isn't
full of text, then AFAIK scrolling won't work, because the scroll
will include stuff from the previous page... but as I've been wrong
about everything else I'm probably wrong about this too. Also I'm not
sure what the implications of the margins being set to 6 are... nor
if this works when the formatForPrinting is set (I suppose so,
otherwise what would be the use of it?). I'll experiment.

It gets worse! I see now that the script can't know the exact number
of lines that will be printed without clipping on a properly
formatted page under Windows! What I can't understand (as with other
aspects of printing) is why so few developers seem to care about
this. Not everybody reads stuff on the screen: for example teachers,
I find, want to carry bits of paper away with them (such as student
reports) even if the actual app is a highly interactive screen-based
thing.
