The "OP" has nothing against Windows, as long as others have to use it :-)

And, if you have a closer look to what is being installed, then you find
out that not only PPD files are installed to your machine -- which are
plaintext indeed -- but also several executable shared objects (Windows-
slang: "DLLs"). They live in

/usr/share/hplip/{fax,prnt,scan}/plugins/*.so

These files are downloaded when invoking "hp-setup" ==> download, and
they ARE closed source.

B.t.w. I also own a Brother Laser printer and this one is accessed via
PCL protocol. PS can also be used. But this is a professional machine for
office use. What we are talking about here is lowcost segment
"Multifunction Fax Printers". Obviously the manufacturers behave
differently in differents price sectors.

Best regards,

Markus
