simple_scanner
This is a simple website that allows a user to initiate a scan against an HP MFP
Install hplip and run hp-setup first to connect the printer
Install nginx (others could be used instead)
copy index.html to the root of the web website
copy scan.cgi to your cgi-bin directory
make sure there is a scan directory in the html root as well for dumping the documents.
This could be so much more complicated (and feature rich) but meets my needs for now.
