I think this is possible:
How I did this:
In Tinderbox, File ▸ Page Setup, I set the page size to A4 (maybe default depending on your locale) and the paper orientation to Landscape like so:
The use File ▸ Print and on the Print pane open the PDF menu (bottom left) and click open in Preview:
From the pop-up menu select ‘Open in Preview’ and you get a ‘preview’ in Preview like so:
I then deleted the blank extra page (‘content coming from Tinderbox and not configurable’), which throws this warning. Don’t worry, no harm done.
Select Print and Preview offers more control than the print dialog in Tinderbox (not sure why - same printer selected in both cases).
My printer’s not playing at present but printing to PDF rather than physical paper at this stage gives an OK output.
Edit menu ▸ Copy View As Image. Switch to Preview, File ▸ New from Clipboard. Then print. Or, better IMO, if you save the file as a PDF you have vector information which scales nicely plus you can still print it.
Untested but my hunch is AppleScript might be a route to go, if you will do this regularly and don’t want to be fiddling with set-up all the time. In the same manner a tool like Keyboard Maestro could be used but the latter might end up actually altering setting where as AppleScript might be able to do this without permanently changing any current settings.
Every day a school day - I didn’t know the answer until I tested all this just now.
