Set the correct PATH environment variables
Why do I get the error code -19?
The error code “PPGM Image Conversion Error -19” usually means that the Print Generation Module (PPGM) cannot find the GhostScript installation. Make sure that the PATH environment variable to the lib and bin folders of the ghostscript installation is correctly set. For example when using Windows 7 (64 bit) and GhostScript 8.71 the correct path would be:
C:\Program Files (x86)\Common Files\Anoto\gs\gs8.71\lib;C:\Program Files (x86)\Common Files\Anoto\gs\gs8.71\bin;
