Scan and recognize data matrix code or text

This is my first post here - I hope this is the right spot for it.

Using a HP 1536 DNF MFP several documents (DIN-A4 format) should be scanned automatically - if possible without manual interaction. Each page should be saved as a seperate file (.pdf, .png o.ä.). On each page an order number is shown as a data matrix code and as a text string.

Our application should copy each scanned (.pdf-)file to our document store and save the file name together with the order number in the database. So after scanning there must be a table (csv file) with e.g. one line per scanned document / file containing file name and order number or the file name has to be the order number.

Is this possible?
Are there any requirements (software)?
What problems might show up?

Thank you in advance.
