caj to pdf conversion is often searched in the context of the export of documents from the database format of China Academic Journals to PDF format.
Especially the western audience might struggle with the CAJ format, due to the limited support for this type of content. As far as we know, the only tool that can view .caj files is the official CAJViewer by CNKI. If it allows printing, then caj to pdf export can be done simply via virtual PDF printer installed.
The issue here is that CNKI discontinued the tool a few years ago, so the real struggle is to find a working download link for this tool.
