"stdin" is a basic knowledge in Linux/Unix: a program is sending
data via a pipe to another program. Example: lp < /etc/hosts

You cannot determine which program it was, neither what the name
of the printed file was, if any. Its impossible.

If you read filenames like "AcroQd8ojy" then its a temporary filename
generated by acrobat, where PDF data is transformed into PostScript
format. The file name is neither given to the print command.

I doubt that you can generate a useful report, as any program can
always pipe data to your printing command. This is one of the
fundamental basics in Unix/Linux.

I think NT (and successors) is offering the same feature.

Sorry.
