I recall something similar happening in one of our schools a couple of years ago, turned out to be a print driver incompatibility. We had to revert those machines from using a more modern V4 driver to a V3 PostScript driver before they would print without crashing again. Initially, given that you've already done everything to repair Outlook minus a full clean reinstall, I'd recommend:
- Stop the Spooler service, clear the C:\Windows\System32\Spool\PRINTERS folder, restart the service, test
- Reinstall the current printer driver cleanly, test
- Revert to a V3 PS driver, test
- Full clean reinstall of Office
- Reimage machine
