Download the current development state (not a weekly snapshot, the
current one is hopelessly obsolete) of CUPS 1.2 from the subversion
repository on www.cups.org and install it. Then go to
http://localhost:631/ and enjoy the new web interface (with
comprehensive help system). If you go to https://localhost:631/ you get
automatically an encrypted connection.
If you have set up an Epson inkjet with Gutenprint 5.0.x, you can even
trigger nozzle checking and nozzle cleaning with this interface.

In the PPD files the entries "Manufacturer" and "Product" should
correspond to manufacturer ("MFG:") and model ("MDL:") in the IEEE-1284
device ID string. More items of the device ID string can be in the
"1284DeviceID" entry of the PPD file.

It seems that the accessories cannot be auto-detected by the computer
with some standard method. The available choices of these options are
selected by the printer manufacturer depending on which accessories are
really supported by the printer.
