The process is that one department creates serialized invoices in Excel and saves them to a USB drive. The next department takes the USB drive, highlights the invoices, right clicks and chooses print. When the invoices were created on the computer running Windows 7 Pro and Office 2010, the files would be printed in sequence based on the file name. Both computers were running Windows 7 Pro and Office 2010.
Both computers were upgraded to Windows 10 Pro, and Office 365.
Now when the same process is used, the invoices are no longer printed in sequence. There does not seem to be any rhyme nor reason to the order they are printed in.
