What kind of software would I need in order to scan documents and produce PDF files as the output?
It sounds like you just need conversion software. With PDF conversion, all you need to do is scan any file, and then run the conversion software to turn the output into a PDF. Some conversion software comes with additional useful features, like compression and OCR. CVISION’s PdfCompressor is one such solution. PDF compressor can convert your files, compress them and make them text searchable, all in one easy step.
