Answer
PROBLEM
    NetPrintQueue2Fax printer is unable to process print jobs in excess of 4 GB. No faxes are sent.
  
  ENVIRONMENT
- GFI FaxMaker
- NetPrintQueue2Fax
- All Supported Environments
SOLUTION
    Either split print job into several smaller print jobs or use alternative methods to send large amount of faxes (XML API, Text API,...).
  
  CAUSE
    The Windows Printer Spooler can only handle print jobs properly that do not exceed the file size of  4 GB. Once the threshold of 4 GB is exceeded, the print job will be dropped from the printer queue.
