[cups.general] root and lpoptions

[Minatra, Pat H.]

What I found was that the 'lpoptions -r newprinter' command does not work; however, we are able to use the 'lpoptions -x defaultqueue' does work.  The only other thing is that sometimes this gets changed by someone temporarily and others do not know it so I am wondering, other than going into the website if there is a command line way to see what the default is, either by user or by root.  I haven't found that yet.

Thank you so much and have a GREAT day!

No need to restart cups - lpoptions is entirely a client thing, so
at most you need to restart any applications that are printing
directly via libcups (or logout and login if you aren't sure).

If you just want to remove the options for the default queue, run:

     lpoptions -x defaultqueue

If you just want to remove the newprinter option, run:

     lpoptions -r newprinter

That shouldn't be the case - the "newprinter=true" bit is treated as
an option, and we don't do mapping of queues like this.

We need to be able to support defaults set by an administrator.
Prior to CUPS 1.3, this wasn't possible in the server itself, so
the solution was to use root's client printing options (lpoptions)
to serve this purpose instead.

As for why "lpoptions -o foo" sets an option on the default printer,
that's just for consistency with the "lp" command (which also doesn't
require you to specify a printer name...)
