I've been seeing this blurb print to our system printer for some time now. Any idea what I need to do to resolve it?

Stackoverfow says to upgrade POI to 4.1.0 or 4.1.2. Will HSSFR4 work with those versions? I tested the latest release of POI, and HSSFR4 didn't work at all.

Thanks

Sorry, I have no clue. I haven't used this stuff in over a decade, and neither Java 9 nor POI 4 existed back then.

The latest version of HSSFR4 supports POI Version 3.14 and earlier.
Later versions of POI will require modification to the service program as some of the parameters have been change to enum.
Cheers, Don
