[Bug 32302] Re: Duplicate printers listed when adding HP printer

[Till Kamppeter]

This really cannot be considered a bug of HPLIP, it is a problem of the
printer setup tools. See the 4th comment in this bug report, from Pascal
De Vuyst  at 2006-02-28 21:46:06 CET:

You see the printer twice as it is once directly detected by CUPS
through its "usb" backend and once via HPLIP via the "hp" CUPS backend.

If you run "lpinfo -v" or use the CUPS web interface
(http://localhost:631/admin/) you will also see two entries for your
printer.

In the CUPS web interface you can clearly distinguish the two entries,
all printer setup tools should do so, as it can always happen that more
than one CUPS backend can be suitable for one and the same printer. The
printer setup tools should also recommend the "hp" backend over "usb"
because it supports the special features of HP printers.

gnome-cups-manager is not maintained any more and will be replaced by
printerdrake. printerdrake suppresses the non-HPLIP entry. See also
