BxSmartPrint Pro requires Visual Studio C++ redistributable.
If BxSmartPrint is missing the correct version of the library, printing via BxSmartPrintPro will not work and will give an error containing "PrinterUtil.dll"
Newer version, after 2.1.31 and 2018, requires VC Redist 2015 Update 3
Older versions requires VC Redist 2013
If you are experiencing issues with printouts from version 2.1.31 of BxSmartprintPro onwards and you receive errors containing "PrinterUtil.dll", it is due to a missing Visual C++ 2015 Redist. Update 3.
