LibreOffice print-display blank, prints blank sheet ... LibreOffice was working fine (except for some random crashes - no clue why). Was doing File>>Print>> proper display of the pages to print, successful print. Yesterday, the pre-print display came up blank, print was blank. The issue document is only 73 pages at the moment. Essential the print works ... I'm publishing a book and author depending on me. Action: Logged out of iMac, relog back in. Still blank. Rebooted iMac, still blank. Updated iMac 11.6.8 Big Sur (was updated already, but new? update came in overnight. Still blank. File>>Print Preview DOES DISPLAY, but when I select icon to print, the Print Screen is, as before, BLANK. In addition to Writer, I checked a spreadsheet I print from regularly. That fails to print as well. The page count shows correct page numbers, but as I click through the pages, they are all blank.
Also tried with another printer ... still blank.
