When redistributing the Auto-print SDK with the Document Imaging OCX the lcms2.dll (lcms2x.dll on 64 bit) file has to be redistributed from the Auto-print SDK (both SDKs contains the lcms2.dll). Only Auto-print version 14.41 and newer can be redistributed with Document Imaging OCX.
For licensed demo version of Auto-print SDK and Document Imaging OCX:
Both SDK/OCX contains the lcms2.dll (lcms2x.dll on 64 bit) and eLicense.dll (eLicensex.dll on 64 bit). The lcms2.dll and eLicense.dll have to be copied from the Auto-print SDK to the destination directory which includes your custom application and the redistributable files of Auto-print SDK and Document Imaging OCX.
