I would like to request to enhance the URI examples
in the "Using Network Printers" documentation
http://www.cups.org/documentation.php/doc-1.4/network.html
regarding this by adding the following examples
in the "Internet Printing Protocol (IPP)" section:

ipp://username:password@ip-address-or-hostname/...
http://username:password@ip-address-or-hostname/...

Should I file an STR for this?


By the way:

According to the "Using Network Printers" documentation
and according to backend/lpd.c in the CUPS 1.3.9 sources
it seems for the lpd backend only a username but no
password is possible.

I wonder why the lpd backend does not also support
lpd://username:password@ip-address-or-hostname/

As far as I see the reason is that according to
RFC 1179 "Line printer daemon protocol" there is
no authentication at all in LPD - instead here the username
is only used to describe who has requested the print job.

Is this correct?
