Description:
Just updated both Catalina and LibreOffice.  Printer is Brother MFC-L2700DW.  I can print from all apps except LibreOffice.  When I open document and choose "Print Preview" it looks fine.  When I choose "Print" the preview is blank and the page from the printer is blank. Exporting to PDF is fine. 

Steps to Reproduce:
1.Open document
2.Select Print
3.

Actual Results:
Open document -- select "Print." Rectangular toolbox opens -- options for how many pages to print, one or two sided, etc.  Upper left is small print preview.  This is blank.  And if you click on "Print" key on lower right the paper that comes out of the printer is blank.  

Expected Results:
Open document -- select "Print." Rectangular toolbox opens -- options for how many pages to print, one or two sided, etc.  Upper left is small print preview.  This should show the document as it is.  And if you click on "Print" key on lower right the paper that comes out of the printer should be the printed document.  


Reproducible: Always


User Profile Reset: Yes



Additional Info:
I've used LibreOffice on this Mac for 10 years.  No problem until I upgraded to Catalina 10.15.7.  Any other app -- PDF, Text Editor, Pages, Images from GIMP or Irfanview -- they all print so I assume it's not a compatibility issue with 64 bits.  At this point the only way I can print documents is to first export them as PDFs.
