This fixed the problem with not being able to email invoices.  Either remove the JPG file and replace with text, or replaced with BMP file and its emailing again.  Thanks for the help!

By the way, quickbooks suggested that I update my Windows 10 since there was an update that had an issue with printer spooling, this did not fix the problem as I tried it first.  The issue is the JPG file on the invoice.  Remove and/or replace with BMP file and all is good.
